Ru shrugged and scowled at the question “I dunno, people own all sorts of things” he pointed out, looking down at the small stranger. Then the stranger started talking again, going on about curses in Abaven lands. He drove the other boy's shoulder harder into the earth. ”Hey, you take that back! Absven isn’t cursed” he protested, this was his home “This was your fault, you brought the fireflies here” he accused, glaring down at the boy.

“You can investigate it outside of ABaven lands, you ain’t supposed to be here” he said, getting off the other boy and pulling him roughly to his paws. Keeping his eyes on him in case he decided to do any more tricks. As he moved, the fireflies parted and moved around them. Surrounding them, without actually touching them - other then that one that had landed on his nose.
