Moros would go on to play a big part in human history on Earth. Moros is mentioned in Greek legend as the personification of impending doom and destruction. After his ascension, he began to fear that the Ori posed a threat to him and the other ascended beings in the Milky Way. He decided to retake Human-form on Earth and build a weapon to destroy the Ori (The Sangraal). During this time he lived in England and was referred to Myrddin or Merlin. He entrusted his secret to a small number of noblemen on Earth, among them King Arthur.
