Hi, friends!
Troll is a mythical monster from Scandinavian folklore, it is generally anthropomorphic, a horrible humanoid of great size and brutal habits that lives in caverns or crevices that go deep into the earth.
Blue, gray, or green in color, it measures two to three meters. It has sunken and black eyes that do not support much light, so It works at night.
In contemporary times, they are common characters in fantasy literature and role-playing games, with features more or less similar to creatures of folklore.
