I've seen a few articles claim Riven is an Ahamkara, but do we know for sure? What gives me doubts about Riven being an Ahamkara is that the body/head look nothing like you would expect it to look like from the Ahamkara bones/skulls we've had on our armor. If Riven is a wish dragon, then why does the body bear such little resemblance to the shape of the bones?
