[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.

• 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.

Attire:

• 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.

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/eating 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). Despite being a robot, she looks fully like a normal human and has remarkable human features.
