Not allergic, there just isnt any reason for us to kill a relatively innocent creature to sustain ourselves. However, lets say that we visited a human family and they served us an animal that they'd hunted and cooked; eating it would not do anything to us, good or bad. However, if an Archon killed an ate an animal (without reason since they dont need food), it would be reflected in their bodily light dimming. It would be like if you or I or any other human ate something that was normally considered inedible: it may not adversely affect us, but why eat it? lol
