Assimilate

A loss is always a sobering experience, especially when it's the first loss one faces in their life. Of course, that is only if the party experiencing the loss is graceful enough to accept it and move on. The Rat King was not. He had never faced such an insulting loss in his entire life (in rat years)! He wasn't reconciled with it. He had essentially sacrificed over 98% of his physical growth to save himself from that demon parading in a weak skin suit. How was he supposed to know that it was all a trap and that a great power lay hidden within that smooth, pink, hairless hide over meat and bone? The loss wasn't his fault, it was all that thing's fault, and for that, he would have his revenge!
