As time passed, Sargan proved to be a valuable asset to Rhea's cause, constantly employing his tactical prowess to help her gain more resources and weaken the factions of her brothers.
Through the use of spies within her faction, Sargan had managed to gather crucial information about the movements and whereabouts of her enemies. In fact, he had even managed to differentiate the spies that belonged to which faction.
He used this information to great effect, launching surprise attacks against them and exploiting their weaknesses.
Sargan's efforts paid off handsomely as his tactics allowed Rhea's faction to kill three Demon Kings from Xander's faction and two from Dante's faction.
It was a significant achievement, one that greatly weakened the forces of her brothers.
Rhea was pleased with Sargan's strategies and rewarded him handsomely for his service in the form of Soul Gems.
