Cray

Crays are a nickname for the corrupted crayfish stored near Noble's Castle. When Noble first found the crays, he rounded up every one of them and put them into an isolated lake to prevent corruption from reaching the ocean. The thousands of crays usually hibernate during the winter but can be woken up with increased agitation. Miata uses crays to evaluate what class each student at the castle is.

The crays have hard shells and are very much like enlarged versions of their uncorrupted counterparts. Their brains are located in the center of their bodies, not the head, making them harder to kill.
