Encyclopedia Entry:
Insect-type monsters that have been around since ancient times. They like dark, damp places. Some live in caves, but most live in human homes (under the floor or in the attic) or in warehouses and similar places. They are about the size of a human girl, but are somehow able to live undetected even in small houses. It is suspected, though not confirmed, that they hide themselves with magic.
They have very little in the way of intelligence and cannot speak any language. Their actions are dictated by instinct and motivated by hunger and lust. As soon as one spots a man, she will capture and mate with him.
