Olizan guarded Sanctumyr under the command of Ket Judinor in the name of Lystellbor. That was, until the Legion of the Illuminate arrived and killed/banished their entire fighting force, Celestials turning on their brethren and the soldiers of Eosus claimed Sanctumyr for themselves. Among the angels who fell, Olizan fell to the Iron City of Dis alongside Ket Judinor. He had been staying in the city since, attmepting to form a way to free Ket Judinor from her compulsory seat atop the Iron Stake.
While in his temporarily hallowed building near the base of the Iron Stake, Olizan met Arix and Vijkastra Misseer, who sought to aid him, defeating Fiends across the city and gathering information about the circle for him (movements/behavior of Ket Judinor, possible magical artifacts in the city to help his goals).
