A glaesine-topped tanik workbench dominates the cramped laboratory, one end pushed against the wall so it is beneath an octagonal window. Atop the window-side of the workbench rests a complicated, platinum gem lens assembly. A glass alembic and a star-carved, black marble crucible also congregate upon the workbench. Scorch marks mar the white marble floors, and a curtained arch leads southeast to the main hallway. Shadowed by night, a winter rose bush sits in the lone, unscorched corner.
