Bone Eater

With those words reverberating in your head, a massive shape starts to emerge from the shadows. Something approximating a head—as if modeled in clay by a young child—appears; chalky white, split nearly in half by a mouth over-filled with fist-sized square teeth. The bone eater’s head is supported by several pale jointed legs, like those of a misshapen cancerous crab.

A sharp gasp turns into a wailing scream as Thandiel collapses to the ground, their leg flopping uselessly as muscles no longer connected to bone attempt to control it
