Kobold

Kobolds are massive, bulky creatures made of mud, dirt, rock, and earth that occupy underground caverns, abandoned mines, and dense swamps and forests.

Origin
Kobolds are believed to have been born directly from the sludge of bogs and swamps. They are a collection of natural elements formed together to create a hostile, territorial creature.

Appearance
Kobolds are large, clumsy creatures. They're incredible dumb beasts; all they know is to attack anything that wanders into their territory. Formed from the materials available from where they are born, their appearance varies. However, they all look similar in that they appear humanoid. They have two arms, two legs, and a head with two beady eyes and a large mouth that takes up most of their face, all formed from collections of mud, sludge, and rocks.
