He nearly dropped his weapon in shock, barely able to recognize the weapon that this... thing held. Shock held him for a moment, before he shook himself back to reality, and pointed at the creature, casting a series of spells in rapid succession. Earthbound, to keep it from flying. Dimension door, to force it to emerge near him. Force Cage, to hold it still so he could discover how this abomination had found Bolvar's weapon. And finally Force Wall, in a hemisphere to hold the creature in with him, so he could destroy it after it was done revealing what he needed to know.
