One of the books I brought to Aetryol contained information on the "corpse candles" that inhabit this island. The book explained a process in which a corpse candle becomes sated but only after consuming a droag body. If I kill a droag and take their corpse near a corpse candle I may be able to witness this. Once the corpse candle is sated, Aetryol would like me to use my creature cataloging ability to study it.
