Let me preface this by saying this is not a criticism, and its not another "what I would like to see in ESO" thread. It's a technical question born out of my own ignorance of how to build a game like ESO.
If a non player character exists, so the art and movement is in place, what are the challenges of making that 'skin' available as a new race? So if (just making this up) a blue skinned 3 eyed being was standing by a dungeon entrance giving out quests as an npc, what gets in the way of making the 'race' of that being available as a race of player use?
Thank you for tolerating and educating the unknowing.
