Here me out, Riven doesn't look like the conventional Ahamkara. It's obvious. The collectable ahamkara bones have a more stereotypical dragon/canine skull with a split lower jaw bone. Same goes for the D1 Bad Juju ornament, Dragonsbane... which is odd in comparison to the current Ahamkara based ornament for D2's Bad Juju. The D2 ornament resembles a baby Riven's skull rather than the usual Ahamkara. Could Riven's physical form be for intimidation and not her true form? Maybe all Ahamkara prefer this one form? Or, these are premature Ahamkara which later grow into the multi jawed abomination which is Riven? Edit: The Beast Magic ornament appears to be a War Beast, sorry on my part. Gave me Riven vibes.... but the question still remains! Edit 2: I realize Ahamkara are "shapeshifters" but it's odd to see Riven in her "true form" and be drastically different from the actual bones of her kind. I mean [i]maybe[/i] the taking of Oryx warped her appearance, but I doubt this.
