According to the former priest on The Island, the self-created omnipotent power known as God created the order of Greater Spirits and sent several of these beings to watch over and protect the young Earth. One of these Watchers, the spirit Anum used God's own power, Vril, and created the Ogdru Jahad out of mud. The other Watchers put their seals on the Beast, but it did not come to life until nightfall, when darkness entered it. The Ogdru Jahad birthed the 369 Ogdru Hem which were the first creatures on Earth.
After a brutal war between the Watchers and the Ogdru Hem, the monsters were destroyed and banished from the Earth. Anum then again used Vril to seal the Ogdru Jahad in a crystal prison and banish them to the far corners of the universe. The rest of the Watchers then turned on Anum, destroying his body except for his Right Hand. After seeing all of this God became furious and destroyed the Watchers. Some were cast down into Hell and others banished unto the Earth to breed monsters. After the fall of the Greater Spirits, many of the lesser spirits were allowed to assume form on the Earth.
