Tales of Tolgard
These gigantic dwarfoids have coal-black skin, flaming red hair, and a jutting jaw that the shows their filthy ivory teeth. Adult males tend to be about 12 feet tall and wear sturdy cloth or leather garments with blackened half-plate armor. Fire giants love to hurl rocks at their opponents and often heat them first to make them more deadly. They enjoy all things hot and seek out flaming weapons wherever they can find them.
These giants prefer hot places to dwell in, usually volcanic in nature but geothermal activity or even hot springs will do in a pinch. They tend to live in well organized military groups occupying large caverns or castles and the be led by a king or queen.
