Delas are nearly indistinguishable from Humans. The average height of the Delas is about 6’5 but some are a great deal shorter and taller. The Delas make up the majority of the population of Inner Earth. The levels of technology among the Delas varies by region but their belief and use in magic is generally universal. However, the more technological the race the lesser is their dependence, and sometimes belief, in magic.
The Delas have never really cared for the human’s presence in Inner Earth but they’ve come to accept it and, with few exceptions, generally show little prejudice against humans.
