Eladrin

Eladrin are originally from the Feywild, but migrated to Istria after being beckoned by the elves to join with them and the drow in defense of the magical peoples of the planet in the face of Nordianic genocide. They are widely regarded as third gender by Istrian natives, though they do, in fact, have males and females. Their customs and appearances are sufficiently androgenous, however, that they do not dispute their current category as other-sexed.
