Zuggtmoy is a demon lord ruling over the world Mycorji. In the Demon Spawn War, she opened a rift between the Abyss and the world Bal-Kriav. This rift was unlike any other rift of the time because it was composed entirely of a slime which made it very difficult to repair by the Web's weave spiders. In the area of Bal-Kriav where it touched, it formed a lake of greenish slime that over time formed patches of what today is called green slime. Zuggtmoy's army invaded Faeglor and was opposed by the earthen army of Geb. As a primordial, and former enemy of the angels and gods in the previous titanic war, Geb was limited in the size of forces he could have under his control. As a result, he was hard-pressed in the conflict with Zuggtmoy. Many of his soldiers were captured and pressed into the deadly mines of Siolix. The lucky that survived this ordeal were mutated into the first fomorians.
In 9460 GE, the fomorian Borri Slarek led an uprising against the demons. He was backed in this conflict by earth elementals and whatever other resources that Geb could send to him without drawing the ire of the Quara'tun Covenant. In 9470 GE, Borri Slarek used the hammer Quake to kill Zuggtmoy. This was not a permanent death, for her dark soul was sent screaming back to the Abyss to reform. The death of Zuggtmoy sent her minions fleeing back to their rift, and home to the Abyss.
Zuggtmoy is only a cult power of Bal-Kriav's pantheon. Her influence is limited to a few areas, yet in these areas her forces are very strong. They usually have dozens of black puddings, entire passages of cannibalistic green slime, and a host of other slimes and oozes.
