Grey spent some time with the Faction Leader, but left soon after. He still wanted to continue his training since there was still bits of essence left from the treasure he took from the Second Prince. The biggest gain in their mission wasn't killing off the Princes or leveling the Capital, rather, it was this treasure. The group has been able to grow by leaps and bounds just because of this treasure. Grey's already in the Fifth stage of the Sovereign Plane, yet he could still feel some leftover essence from his share of the treasure.
Void and the bunny leader unfortunately didn't get any part of it, well, it's not like they needed it. Void has grown to the Fourth stage of the Sovereign Plane, and so has the bunny leader. The duo were growing so fast even without the aid of the treasure. Taking into account the number of treasures the duo have in their possession, Grey believed him and his friends paled in comparison to Void and the bunny leader when it comes to treasures owned.
