Could Zed be a Darkin

There's been a lot of speculation about who Zed is given the way his lore was written. I had an epiphany this afternoon... What if he's also a Darkin? It's possible that even the other Darkin wouldn't know (I suppose).

Someone shoot me down if needed, but it seems interesting enough to throw out there. There is evidence that Zed isn't the person that we think, and it could be because he's possessed.
