Rave is with Chaotic and sees the others. He starts to boil. His features start to change as he activates his dark magic. "Just a little bit of fun. 1 pony against many, seems hardly fair. Let's make it a bit more interesting and more.... fair...". He conjures forth about 30 shadow like creatures, using the horn to fuel him. He points and they seem to attack the rest. "That should keep the a bit occupied" he said madly.
