Interdimensional Alliance

The Interdimensional Alliance (commonly abbreviated IDA) is a multilateral cooperative body spanning hundreds of known universes, founded on the principles of mutual defense against extradimensional and anomalous threats, economic neutrality, and non-interference in member universes' internal affairs. It is one of the oldest known organizations of its kind, predating many of its member civilizations' recorded histories, and operates under the stewardship of its founder and primary coordinator, Azaelith Crystallight (also known as Moonlight Angel), a Crysalis entity of disputed cosmic classification.

1. Overview

The IDA functions primarily as a collective security organization. Member universes retain full sovereignty over their internal affairs; the Alliance activates only in response to threats classified as extradimensional or non-native to the script of a given universe — entities, phenomena, or incursions that fall outside that universe's natural developmental trajectory.

The organization is headquartered in a pocket reality designated Planet Paradise, maintained by the founder. Alliance meetings are held at rotating neutral venues, with the Astral Express (a non-affiliated independent vessel) having served as a notable recent meeting site.

Membership spans governments, independent military organizations, nomadic peoples, supernatural factions, and extraterrestrial civilizations. As of the most recent general assembly, the IDA formally welcomed the Interastral Peace Corporation (IPC) and the Xianzhou Alliance as members, alongside the crew of the Astral Express.

2. History

Early Period

The IDA's founding predates most of its current membership by thousands of years. Its origins trace to Azaelith's early travels through the multiverse, during which she observed recurring patterns: civilizations destroyed not by internal conflict or natural entropy but by incursions from entities operating entirely outside universal law — creatures of the Lovecraftian mythos, anomalous phenomena later classified by the IDA's research division, and extradimensional parasites with no natural ecological role.

Initial alliance-building was informal, relying on Azaelith's personal relationships and the quiet integration of the Crysalis banking infrastructure across participating economies — a neutral monetary exchange system that had been operating for millions of years before many member civilizations were aware of it.

The first formal structure emerged when Lelouch vi Britannia, conscripted into the Alliance at age sixteen following the conclusion of his universe's primary conflict, was appointed as the Alliance's public-facing diplomatic representative. He remains this figure as of current records.

Expansion Period

Over subsequent centuries and millennia, the IDA absorbed or established formal relations with a wide range of civilizations, including the Imperium of Mankind (secured following Azaelith's resurrection of the Emperor of Mankind and a political marriage of alliance), various demon lord factions, the SCP Foundation (following a catastrophic containment breach that brought the Foundation under IDA oversight), and numerous independent organizations.

The addition of Norman (of the Promised Neverland universe) as a secondary diplomatic coordinator and strategic director formalized IDA's internal command structure. Norman oversees inter-universe military coordination and serves as the primary liaison to demon-allied forces following the IDA's acquisition of contracts from the TTDOD universe.

Recent Period

The IDA's most significant recent expansion occurred with the formal acceptance of the IPC and the Xianzhou Alliance as members, following first contact brokered aboard the Astral Express. This brought the IDA into formal relationship with one of the largest commercial-political entities in a major star system, as well as the oldest organized military force specializing in Abundance-path anomalous threats.

3. Organizational Structure

The IDA operates on a consensus-and-contribution model rather than a hierarchy. Voting weight in general assemblies is proportional to contributed resources during joint operations, though charter rights apply equally to all members.

Founder and Primary Coordinator

Azaelith Crystallight (Moonlight Angel) holds no formal title within the IDA beyond founder. She does not attend most diplomatic functions directly. Her role is best described as architect and final arbiter — she sets the founding principles, maintains the SCP division's highest-clearance decisions, and retains veto authority over operations that would violate core charter principles.

Diplomatic Directorate

Lelouch vi Britannia serves as the IDA's face in all formal negotiations and public functions. His decades of experience navigating hostile political landscapes across universes make him the Alliance's most effective spokesperson. He is accompanied at major functions by Norman, who handles strategic analysis and logistical planning.

Research and Containment

The IDA-SCP Foundation (see Section 6) operates as a semi-autonomous research and containment body under IDA oversight. Access is heavily restricted and considered a membership privilege.

Military Coordination

Inter-universe military operations are managed through rotating coordination councils assembled per-operation. Permanent standing forces include Azaelith's Space Marine chapter (gifted by the Emperor of Mankind as reward for his resurrection) and various contracted beastman and demon military assets.

Economic Oversight

The Crysalis Banking Consortium operates as the IDA's economic infrastructure, providing currency exchange, neutral financial arbitration, and cross-universal trade facilitation. It is explicitly designated as neutral infrastructure rather than a competitive economic body.

---

4. Membership

Membership is extended to the largest functioning governmental, military, or organizational body of a given universe, following IDA vetting protocols. The IDA maintains an internal reference system using fictional media designations from a restricted-access universe to facilitate first contact and threat assessment.

Founding and Long-Standing Members include (among many others): the Imperium of Mankind, various Fate/Stay Night factions, Code Geass's post-Zero Requiem structure, and the remnant Promised Neverland survivor leadership.

Recent Members include: the Interastral Peace Corporation, the Xianzhou Alliance, and the crew of the Astral Express.

Special Status Members: The Xianzhou Alliance negotiated independent acknowledgment rather than IPC-satellite status — a charter accommodation unique to their membership agreement.

5. Core Principles and Charter

The IDA Charter rests on six pillars:

I. Non-Interference. Member universes' internal affairs, political systems, and natural narrative trajectories are inviolable. The IDA does not intervene in internal conflicts, governance disputes, or natural evolutionary processes.

II. Script Integrity. Member universes' canonical developmental trajectories (colloquially "scripts") must be preserved. IDA operations are prohibited from altering fixed narrative points or indigenous developments.

III. Mutual Defense. Extradimensional threats — entities, phenomena, or incursions non-native to a universe's natural order — trigger collective IDA response. The operating threshold is roughly: if it shouldn't be there and it kills everything including the bacteria, it's ours.

IV. Economic Neutrality. The Crysalis banking infrastructure operates as a non-competitive neutral exchange system. No member may weaponize economic access.

V. Anti-Temporal Interference. Time manipulation within or across member universes is strictly prohibited.

VI. Sovereign Asset Control. Joint IDA assets (including SCP-contained entities, ark technology, and shared real estate) are distributed and governed through collective agreement. Individual universes may not unilaterally claim or exploit shared assets.

6. The SCP Foundation Division

Following a catastrophic containment breach in the SCP Foundation's native universe, the IDA intervened and absorbed the Foundation under Alliance oversight. The IDA-SCP Foundation now operates as the Alliance's primary research and containment body for anomalous entities.

Access to Foundation resources is a membership privilege, not a universal right. Member civilizations may nominate scientists for part-time Foundation research roles, subject to vetting.

The Foundation's containment protocols have been expanded to accommodate extradimensional anomalies not previously categorized in Foundation literature. Stellarons (Honkai: Star Rail universe), Wanderers (Love and Deepspace universe), and related phenomena have been provisionally classified as Keter-adjacent pending further study.

Fog Condenser Technology — developed to counter the miasmic fields employed by many extradimensional entities — is distributed freely to all member civilizations. Distribution is intentionally unconditioned; the IDA recognizes that hoarding defensive infrastructure serves no one.

---

7. Economic Infrastructure

The IDA's economic neutrality is maintained through the Crysalis Banking Consortium, a system that has operated covertly across most member universes for millions of years prior to the IDA's formalization. It provides:

• Cross-universal currency exchange at neutral rates
• Secure asset transfer between universes
• Financial arbitration for commercial disputes between member entities
• Funding mechanisms for joint IDA operations

The Consortium's pre-existing integration into IPC economic systems was confirmed during first-contact negotiations as evidence of long-term operational neutrality — a fact that significantly accelerated IPC membership acceptance.

8. The Sky Passages

The IDA maintains a network of dimensional transit hubs designated Sky Passages, operated exclusively by Crysalis staff. These facilities externally resemble pagodas and contain considerably more interior space than their exteriors suggest. They function as the IDA's primary logistics infrastructure for inter-universe travel, personnel transfer, and rapid response deployment.

The Crysalis stewardship of Sky Passages reflects the species' historical role as dimensional travelers and their cultural mandate to maintain neutral access to dimensional transit — described in Crysalis cultural literature as analogous to the relationship between airspace and aviation authorities.

---

9. Military Doctrine

The IDA does not maintain a standing army in the conventional sense. Military operations are assembled per-threat using contributed assets from member civilizations, weighted by investment level.

Investment and Allocation: Member contributions to joint operations determine proportional asset allocation in post-operation distributions (including contracted personnel, recovered technology, and territorial claims over seized universes). This creates a self-reinforcing incentive for member investment.

Vetting Protocols: All allocation of contracted sentient personnel (including demon-contracted forces, SCP researchers, and Alliance conscripts) is subject to independent vetting by Alliance command. Nominations must come from verified notable figures within member organizations. Blacklisted individuals may not receive allocation regardless of organizational standing.

Operational Philosophy: IDA operations favor strategic preparation over force. Founder Azaelith has noted that "enemies' inability to collaborate is our greatest asymmetric advantage" — the IDA's coordination capacity is its primary force multiplier.

10. Notable Events

The Stareater Deletion — An Abundance-path world-consuming construct was destroyed by an unaffiliated entity prior to formal IDA intervention. The incident is unattributed in official IDA records.

Amphoreaus Resettlement — Approximately 1,000 surviving Avgin were located through IDA-affiliated black market channels and resettled in Imperium-administered territory, pending permanent relocation. The operation was privately funded.

First Contact: IPC and Xianzhou — Formal first contact was conducted aboard the Astral Express, resulting in concurrent membership of two major Honkai Star Rail-universe powers. The Astral Express crew independently petitioned for membership at the conclusion of the same session.

TTDOD Universe Acquisition — The IDA voted to acquire demon-contracted forces from the TTDOD universe following a majority vote at general assembly. The Astral Express crew voted against the measure. The operation was conducted using IDA military assets and rune-based containment protocols developed from cross-universe demonology research.

11. Criticism and Controversies

The IDA has faced internal debate on several points:

The Non-Interference Paradox: Critics note that the TTDOD acquisition represents a tension between non-interference principles and active intervention in a universe's internal structure. IDA leadership maintains the distinction between internal affairs and asset acquisition for external deployment.

Script Integrity: The deletion of the Stareater construct occurred prior to a canonical narrative beat assigned to it in certain universe trajectories. IDA archivists have noted a resulting gap in at least one known universe's developmental record. No formal corrective action has been taken.

Transparency: The IDA's use of a restricted-access fictional media universe for intelligence gathering has been debated internally. Access to this resource is limited to founder-level and senior diplomatic personnel.
