Tremas's Triscorder

A compact, handheld scientific instrument with a smooth metallic casing and a central sensor array that glows faintly blue when active. Tremas wields it to scan energy forces and probe Kassia’s unnatural collapse, revealing inconsistencies in her vital signs. The device hums softly against the unnatural silence of the Sanctum, its role as a bridge between shared reason and bureaucratic tyranny clear as Kassia falters under its scrutiny.
