Geb and Agni were once two separate entities, Geb being the god of earth and Agni the god of fire. After the discovery of the Heart of Fire, the two entities were merged into a single deity. The joint entity quickly attracted smiths, who utilize both earth and fire, as his core worshippers. Although most of his worshippers are metal workers, miners, and fire giants, he also receives adoration from soldiers and crafters who work with stone, clay, or earth.
The god is shown as a dark-skinned, bearded man wearing a smith’s apron. In one hand he holds a miner’s pick and in the other a smith’s hammer. Shrines are always carved from stone, basalt (a volcanic stone) being preferred. Shrines are common outside mines and deep caves, both gateways to Geb-Agni’s subterranean palace. Temples are always built underground, ideally around a hot spring or mud pool. Whether or not these are available, the clergy ensure that roaring fires keep the temperature inside a stifling 100 degrees plus.
Traditionally, Geb-Agni’s priests follow his earth aspect and wear brown robes, while his paladins follow his fire aspect and wear red robes. In reality, the clergy worship both aspects equally, the names being a leftover from the earliest days of the union. The clergy are a mixture of stoic resistance and furious rage, as befits their god, and one can never tell how a cleric will react to a given situation. Ceremonies involve fire and sound. Celebrants jump
over ritual fires, which release sins from their spirit. Others bang hammers on anvils or rocks to drive away the sins. Fire walking is considered necessary for followers who have committed grave sins.
