In the Faeglor Front (228 GE - 261 GE), the army of Geb battled the forces of the demon lord Zuggtmoy. Many of those captured by the latter, if not eaten or turned into fertilizer, were put to work in the dreaded mines of Siolix. An area interlaced with veins of deep rock, it killed many and mutated others. One of the humanoid mutations to come out of Siolix were earth giants mutated into a new Giant sub-race named the Fomorian.
In 259 GE, the fomorian Borri Slarek led an uprising against Zuggtmoy. Two years later, with the hammer Quake, Borri banished Zuggtmoy back to her abyssal home world. The Fomorian people followed Borri until his death, then after failing to pick a leader, they split into groups and scattered.
The Fomorian are credited with creating the first Spriggan from captive Svirfneblin exposed to deep rocks.
