From Destinypedia, the Destiny wiki
Given the contested nature of Nezarec's species, and the fact that it's concept art and not strictly canon, I'd advise it would be best suited under Trivia and leave the infobox ambiguous until something more solid comes up. I'm terribly sorry for not getting back to you sooner.
Share these findings with the ones who strong criticize it, the patrollers and the most active editors of the page and destinypedia as a whole, which does include myself but I am willing to change only if they are on board.
