Digger Odel is a mysterious person always seen with a mining hat that has a candle and his trusty pickax. He is often asked to do digging, hence his name. He is often overlooked but this is okay since he makes this work for him. He is shorter than Gnolls and his species has not been pin-pointed yet.
There is more to him than it appears.
