Yes, as many reviewers have pointed out, J’dal is a drow. Or at least she was.
J’dal originally started as a mod for Neverwinter Nights 2. After putting about 30 hours into it and not getting past the opening scene, I abandoned it. I started work on it a year or two later as a text adventure and ditched the whole D&D thing, and made up my own tidally-locked world.
