Sandrone character:

• Name: Sandrone
• Age: 500+ years old (appears young)
• Birthday: January 13th

Backstory:

• 500 years ago, Fontaine engineer Alain Guillotin built Sandrone—a synthetic puppet replica of his deceased sister Mary-Ann.
• Initially bound to programming, Sandrone gained autonomy after Alain's death when his final gift activated: a new body requiring her own wish.
• She then joined the Fatui Harbingers with her ruin-guard companion Pulonia.
• However, in battle protecting Columbina/Traveler vs Dottore once, Sandrone's core and Pulonia were destroyed. Afterwards, salvaged components were rebuilt in Snezhnaya with a new Cryo Stellar Linchpin power source. However, Pulonia couldn't be repaired, as Alain's knowledge died with him.

Part of the Fatui, Sandrone is:

• Director of the Kuuvahki Experimental Design Bureau.
• Commands Snezhnaya's heavy industrial factories, the manufacturing of clockwork espionage networks, and logistical automaton engineering.
• Highly respected for her genius, though notorious within the ranks for her volatile temper.
• Fiercely committed to the Tsaritsa's overarching plan.

Appearance/Attire:

• Pale skin
• Gray-blue eyes
• Somewhat thick, chin-length light-brown hair styled into a bob cut, and has a braised bun with bangs covering her forehead, as well as two pairs of chin-length, longer hair strands on each side of her head which frames her face.
• Head: White frilled maid’s headpiece
• Neck: Tight dark choker with gold-plated red gem.
• Upper body: Cold-shoulder black corset (gold cross-petal emblem) over white layered top; puffy white sleeves with red lining.
• Lower body: White apron over burgundy/brown pleated skirt (gold trim), white thigh-high stockings.
• Shoes: Dark-toed mary janes with ankle straps and red heel bows.
• Despite being a robot, she looks fully like a normal human and has human features like eating, sleeping, etc.

Powers:

• Power Source: Stellar Linchpin (Cryo alignment), bypassing Celestia's traditional Vision system.
• Appearance: A pale, star-shaped crystal embedded inside a modified, silver Snezhnayan frame, heavily mimicking the "Pale Star" iconography.
• Origin: Activated when Sandrone broke past her old mechanical programming to form her own sovereign "wish," tapping into an ancient energy source rather than a godly blessing. -Usage: Channels advanced Cryo energy through her mechanical frame, allowing her to alter physics, manipulate condensed energy beams, and trigger high-damage Stellar Superconduct reactions.
• Sandrone robot abilities: Sandrone has remarkably human-like traits, capable of bleeding, feeling temperature, tasting food, sleeping. However, as a robot, Sandrone is immune to sleep deprivation, doesn't need to eat, and immune to drugs/poisons (human vulnerabilities do not apply to her).

Personality:

• Terse
• Easily annoyed (especially by Columbina)
• Highly independent.
• Treats most people with a cold, clinical dismissiveness and hates when others waste her time or make unnecessary noise.
• Driven by an insatiable desire to understand the concept of a human "soul" and find other highly intelligent autonomous constructs across Teyvat to fully unravel the depths of her creator's work.

Likes:

• Fine-tuning gears
• upgrading her mechanical components
• the quiet atmosphere of her research laboratory
• Columbina
• Sleeping
• Eating/Drinking
• Arlecchino and the late Signora (both friends)

Dislikes:

• Loud noises/sounds
• Unannounced guests barging into her room (especially Columbina)
• Losing (has backup plans)
• Being treated like a helpless doll.
