Flesh Eating Worms

Flesh Eating Worms are a very common species inside most of the cursed castles. The origin of them are unknown, though several theories have been stated by researchers.

Prof. T. Dalton Theory
The worms had not always been accursed beings, but due to their diet of zombie corpses, have absorbed the curses themselves. Being in this state, the innocent earthworms had no control of their hunger or what they ate, and thus became Flesh eaters.

Dr. Šjlivović's Theory
The deadly worms found in the depths of the castles are a very ancient species of earthworms, dating back to 3.000.000 BC. At the time, earthworms were carnivorous and somehow survived miles below the surface of the earth, in dirt. But later on escaped during the digging of the tunnels when the castles were built. Because of the extreme climate changes during that time period, the earthworms being stuck beneath the surface, (exposing them to higher levels would instantly kill them) remained in the depths of the castle's tunnels.
