History
First mentioned around the time Linley was in the Mountain Range of Magical Beasts. Olivier apparently became a saint between the age of 30 - 40. He was known as a prodigy, whose actual talent rivals that of Linley. As soon as he became a Saint, he beat the Stellar Sword Saint Dillon in three hits, and soon after challenge the Saint Haydson, whom he lost too.
After returning from his training at the Arctic Icecap, he once again challenged Haydson, but this time he managed to kill him with just one strike[1].
During his stay in the Necropolis of the Gods, he was mentioned to have a strong soul which is useful to defend against spirit attacks.
He is also the only known person (so far mentioned as of book 11) to have been able to use both the Profound Laws of Light and Darkness simultaneously, which is a result of his Soul Mutation.
After the events of the Descent of the Gods and after he learns of the death of his brother, Blumer, he departs for the Infernal Realm alone, wanting to adventure and discover new heights.
Trivia
His ability to wield both Profound Laws of Light and Darkness simultaneously also humorously affects his hair color, turning it half white and half black.
