Siblings

Five days training had been more than enough for Michael to determine Mekhaz and Thaor's combat prowess, their weaknesses and their most exceptional advantages.

Combining the two frontline fighters, who had exceptional endurance and useful physical Soultraits, with Kaleb's Frozen Nova, and Michael's great versatility, they would have good chances of overpowering other teams. All they missed was one more member – preferably an Awakened with a Support-type Soultrait, or maybe even a healer. 

Kaleb was great at controlling the surroundings with his Soultrait, and he could inflict a considerable amount of damage as well. Michael, on the other hand, was more of an assassin, a long range fighter and everything else except a Supporter and a Tank. But the latter could be solved by Thaor and Mekhaz rather easily.
