Ollerus

Aurrelus has been called the mage closest to becoming a "maijin", a "God of Magic". He is a mysterious fellow, and by far one of the strongest characters in the Index universe

Profile
He first appeard in volume SS2, he came to Academy City in order to put across a point to the Academy City's Board of Directors - that if they misuse the 'gemstones' they took in he will step in to stop them. He is confronted by 9 of the 10 Misaka Sisters remaining in the city, he manages to defeat them all effortlessly. He is then confronted by Sogita Gunha (the 7th level 5) currently on patrol as a member of Judgement. Gunha after seeing what Aurrelus did to the sisters deems him a threat and attacks. Aurrelus then uses the deffensive spell called [|Hliðskjálf(Hlidskjalf)] in a offensive way which floors Gunha and knocks him down into the ground. Gunha however proceeds to get up without major injuries, and charge valiantly at Aurrelus once again only for the same result to occur. Gunha once again gets up and charges and the battle cuts off there, we later learn that Aurrelus was victorious and Gunha is beaten into the ground. The difference between Gunha and Aurrelus' powers were so large that though Gunha took Aurrelus as a serious opponent and went all out Aurrelus was only toying with Gunha.

Aurrelus weilds the power of the Northern Throne, and his power has been described as "imcomprehenisble and inexplicable". He is currently being pursued by various magical organizations seeking his power, but he has mangaed to elude all of them. He is in the company of Silvia, a saint, who is cruel to him on the surface but still cares for him deep down.

Personality
Aurrelus has a kind heart, he squandered the once in 10000 year chance to become a "maijin" (or magician god - one who's magical power has reached the level of divinity and can bend all natural laws) in order to save a cat. He also destroyed a human trafficking organization and saved 100 children, when he did not need to.

Abilities
He almost became a god of magic, but didn't. He can use the knowledge from a lot of grimoires. Until now he only showed one of his ability in the SS2 novel:
 * Hliðskjálf, it is his power to change life energy and normal magical power into an unexplianble type of power. The power by its nature cannot be described, can't be explained, and can't be comprehended. Since the power cannot be comprehended, there is no possible defence to stop it according to Aurrelus. Also, the actual Hliðskjálf (which is the throne of Odin) doesn't have any offensive function, by forcefully using Hliðskjálf in offence makes his power even more unexplainable. He uses Hliðskjálf due to his own mana is too special and can't be used with normal magical powers. In other words, he needs the unexplainable energy to be used up by Hliðskjálf to prevent self-destruction.
