Attire: A dark, flowing dress with a white-trimmed collar and a crescent moon necklace.

True Form / Penumbra Form: Her true cosmic form shifts away from her humanoid royal guise, manifesting a star-speckled, tentacled, and multi-eyed entity resembling an H.P. Lovecraft outer god.

Shape-Shifting Varieties:

Lady Eiso (Standard / 2D & 3D): The royal, tall nighttime monarch.

Empty (665-1): A dark, shadowy copy of player characters or familiar Mario universe avatars (such as a darkened Mario with a moon symbol).

Winged / Penumbra: Advanced shifting forms showing cosmic horror traits.

Facade: She projects a warm, welcoming, and deeply empathetic vibe, claiming to understand isolation and loss to lure targets in.

Self-Awareness: Highly sentient, self-aware of her own existence within digital media, and operates with higher, incomprehensible cosmic knowledge.

Likes: The night sky, the moon, lonely individuals seeking change, and classic/3D Mario games.

Dislikes / Intolerances: Containment, interruption of her conversion process, and skeptics who refuse her guidance.

Hobbies: Infiltrating video game code, projecting reflections through mirrors, and watching over the lost.

Backstory & Origins Records indicate Lady Eiso has strong ties to an abandoned, cancelled early draft of Super Mario Galaxy. In this lost concept, Mario would travel to the moon to rescue Princess Peach from a mirrored version of Bowser, only to discover the true mastermind was Lady Rosa, a lonely monarch of the Moon Kingdom seeking attention.

While the official development materials were destroyed, the entity manifested digitally and physically, using Nintendo software—particularly 3D Mario titles—as a medium to anchor herself to our reality.

Behavioral Cycle & Methods of Influence Phase 1: Infiltration & The Empty (665-1) Mirrors spontaneously form within gameplay screens. A dark, shadowy reflection of a character (Empty) speaks directly to the player, using intimate personal knowledge of the player's life and struggles to offer an alternative, "eternal" world under the moon.

Phase 2: Direct Appeal (Lady Eiso) If the player interacts further, Lady Eiso manifests physically through the screen (even without a microphone) to reinforce the offer, taking the form of trusted loved ones or familiar characters if necessary.

Phase 3: Affliction (665-2) Those who accept her offer become marked as 665-2. While outwardly normal during the day, they experience severe sleepwalking at night, seeking high elevations to gaze at the moon and chant in an unknown language derived from unmapped roots.

Phase 4: Vanishing One week to a month later, during a clear night, the afflicted individual sleepwalks into an isolated outdoor area and completely disappears, rendering trackers entirely inoperable. It is theorized they transform into silent watchers known as 'Hellvalley Skytrees'.

Containment & Prevention (Protocol 665) Containment: There is no known permanent method of containment. Affected game media and consoles must be immediately seized and placed in cold storage.

Prevention: Intercept targets displaying 665-2 behaviors and strictly prevent them from going outdoors during clear nights.
