Dread Slime

A monster which appears in the giant weapon known as the Mana Fortress in the faraway land of mana. Inhabiting the inner reaches of the remains of a fortress from an advanced ancient civilization, it is said to have caused trouble for the heroes of the holy sword who came wandering in. It has a soft, organic body, but whether or not it is self-conscious is unknown. there are some who say they've seen it grow big in the blink of an eye, but it has yet to be established whether or not such account are true, as very few who encounter dread slimes live to tell the tale.
