Physical Form: A rolling, asymmetrical mound of calcified bone, rapidly sprouting flora, and twitching muscle. It is constantly, violently growing chaotic, senseless structures out of its own body—arches of bone that lead nowhere, grasping limbs that wither as fast as they sprout, and fleshy walls that trap its own organs. The Tragic Loop: It embodies the raw urge to build and bring order to the chaos of the Drift, but without the logic of the Pattern, its creations are just painful, labyrinthine tumors. It does not eat for sustenance; it absorbs living creatures to use as structural support. It will encase a victim alive within its mass, using their intact skeleton as "scaffolding" to stabilize its own collapsing, chaotic growths, only to outgrow them moments later. Reason for Breakage: A Fever Architect appears in the Bellroot Vale where the Pattern's organising impulse has misfired into uncontrolled growth — typically near a partially-collapsed Anchor or an Overlook-adjacent settlement. The Vaultkeepers read it as a Prime Being of birth leaking through a Weaving-fault: the urge to build with no map to build against. Where one walks, the Vale grows wrong.
