A nightmarish approximation of a dragon, with an elongated black translucent body shimmering with power and diaphanous wings glistening with coursing sinew.

A sendrak is a nightmare-made-flesh, manifested in the world by an entity of chaos and madness to break down the barrier between the material plane and the world of dreams.
