Parthian Ancient Country, Rock Cellar City.
It had been two days since the three Demons were banished back.
During this time, Aiwass's convoy had not entered the Rock Cellar City but continued to wait outside the city. Aiwass, accompanied by several Ritualists, entered to study the ritual. He also brought Sherlock to help cast curse resistance spell defenses.
Although the Troll Wizard who continuously used "Curse Nova: Petrification" as the ritual array's base had been dealt with by Aiwass — by the way, Aiwass named that skill since he didn't know what it was called — there were still remnants of the active curse.
As the ritual base, the Troll Wizard's soul was almost burned out.
In fact, even if Aiwass didn't intervene, the Troll Wizard would probably burn out in some time... say one or two weeks, and then die completely, turning into ashes.
Aiwass killing him truly gave him relief, allowing his soul to enter the Dream Realm.
