This does look like Dark Sun. If it is Dark Sun, they will have to tone down some of the setting; there's no way around it. 

In OG Dark Sun, the elves breed through *unwanted mating*. Also,*unpaid internship* is prevalent through most of the setting, let alone many of the species having specific real world unflattering racial analogies (i.e.: halfling cannibals/pygmy cannibals; muls as an *unpaid intern* species).
