Brollachan
About
A Brollachan is a dark, shapeless thing with eyes and a mouth but no settled body of its own. It pools beneath bridges and in roofless ruins, repeating the last words spoken nearby because it possesses almost no language or identity. When frightened or commanded, it pours into an unattended skin, cloak, or hollow object and moves in an imitation of life.

No Name of Its Own: it has -2 Mind against commands built entirely from words it has repeated during the encounter. Bright, unbroken light prevents it from entering a new shell.
