Runekeeper was the original cosmic god of magic and possessed The Book that contained the ultimate secrets and spells of the Multiverse. He was one of the Cosmic Deities and sought order and organisation for magic throughout the NeSiverse. The Earth, however, was outside his dominion until the Ancient One's bindings were dispelled and he attempted to claim bring order to Earth's magic. He was, however, destroyed by the backlash caused when the hedrons, hidden within the underwater ziggurat, were activated in the war against the Highemperor. The Book was left behind and claimed by Hermes Trismegistus who took on the title of 'Runekeeper' for himself.
Highemperor and Soriel's Adventures in SPAAAAAACE!!!
The Big O was de facto ruler of the NeSiverse, as bestowed upon him by the 12 God-Monarchs, but he did no actual ruling. Instead that task was left to Fladnag the White, the grand vizier. During his quest for information on Earth's magic, Runekeeper sought out Fladnag only to find that he had been usurped by a man known as Highemperor. Highemperor, despite being born on Earth, didn't know who the rightful god of magic was on Earth. Soriel, Highemperor's right-hand man, suggested Runekeepr just google[Ext 1] it. A quick check only revealed the names of Hermes Trismegistus and Thoth as likely candidates but still no definitive answer. Highemperor, new to the job, had no answer for him and dismissed Runekeeper. Highemperor, unable to help anyone that applied for his aid, would eventually give up his short reign and return it to Big O and Fladnag[Pan 1].
