Sterl quickly grasped the situation.
The sisters' plan was straightforward: The Hall of Valor, at least on the surface, did not permit mutual slaughter.
The genius of the Nether Soul clan, who absorbed various slaves under the guise of taking apprentices, was known as "Edward," a mid-tier legend of the clan.
Sosia and Sonis were soon to meet "Edward" to formally become his apprentices. As their master, Edward had the right to make his disciples assist in magical experiments.
If these experiments failed, it would be reasonable for the sisters to die as a result.
Sosia and Sonis' only chance at survival was to latch onto someone powerful during the time before Edward summoned them after they completed the extreme trials.
Their idea was simple: find a powerful figure to pose as their follower and challenge Edward on their behalf once they met him.
It was a risky and straightforward plan.
