Bilbo closed his eyes then suddenly blade came thru the creatures head, taking the head off. As the creature fell a white haired warrior stood there, panting. He said "group together! They don't attack packs, only lone prey!" The warrior ran to take out another monster, the Wargs pack heading towards them. He cursed and said "now would be a time for your aid!" A hooded figure jumped in front of Thorin and the others, a staff in hand and a short blade in the other. 

They turned to the other creatures and muttered softly under their breath and suddenly shadows jumped up and wrapped around the hybrids, holding them down. The warrior smirked and said "cut them down quickly! Before their friends show up!"
