Remember, Kemarus is tamed now. You can play off that... you can have an enraged version of Kemarus, or even build support for him through other creatures and spells.
For the Demnus, how about using one of my mechanics called Feed N (Whenever a creature dealt damage by this creature dies, put N +1/+1 counters on this creature.)?
Did you read what came after the story? The assignments? I gave you the R/B guild leaders after @Grimshac couldn't do it. I could pass that down to someone else if you want.
