Gm'a is the troll god of rocks and earth. Dwarves believe that he is a combination of the aspects of Grawl, god of blacksmiths and war, and Geminite, goddess of gems and riches. In troll mythology, he hatched out of a stone egg and the shards of the egg created the world. Some other shards created the moon. The yolk than spilled forth and wherever it touched, life sprang up.
