He had not been expecting to be asked such a thing as he walked back into the cave. What did he eat? His eyes moved to the man. "I feed on the energy and chi of other living things" he says, "essentially their life force and power." Blunt enough, and it was true. He could take a little and the person would heal, or a lot and end up killing them. It depended on how hungry he was, and how he desired to go about this feeding. He moved to the table, picking up a glass of wine to drink. His eyes not on the other for now, he would let him take in that bit of information. "I am able to sustain myself on normal human food as well though, or from drawing from plants instead of animals or human beings..." he adds after a moment.
