Guardian beast
Mechanics diagram
Activation
  • Ambient; the duplicate room manifested around the household without Marayam's awareness.
Conditions
  • One-way boundary: anyone who leaves cannot return or see inside (demonstrated by Belerainte, ch. 375).
  • Those inside vanish from the real room's perspective.
Effects
  • A concealed duplicate of the prince's quarters — the safest room aboard.
  • Growth tracking the child's development; adult form unknown.
  • Renders the household unlocatable — Benjamin's soldiers could not find Marayam even under Special Martial Law (ch. 413).
Assessment
Description

A serpentine beast whose known power conjures a perfect duplicate of Room 1013 behind a one-way boundary: the household lives inside it, invisible and unreachable, while the real room reads empty. Biscuit identified the boundary type on-page; the beast also keeps growing with the child, toward a ceiling nobody knows.
