I finally found the source of the creatures deep in the forest. It was a woman who was chanting and surrounded by a pentagram. I blasted another one of the creatures away, then aimed a palm at the woman, blasted her off her feet, and screamed through the air. The spell circle started to spin and dissipated without someone holding the portal open.
The creatures around me melted now that the portal and their energy source were gone. Each one of the were-sphynx cats turned into a black ooze as I walked over to the idiot groaning in pain on the ground. I was trying to figure out what I should do with them, but I didn't understand why this person was trying to attack me. Albeit it, I did walk in and find them; they were close enough to be considered a problem in my books. There was also no getting around that annoying sound.
