I was both interested, and slightly disappointed to learn that Seiryu is going to be a snake Auspice. Admittedly, I base this assumption on a single image from the Requiem for Heroes patch page, but it seems likely to be the case.

The reason I find it somewhat disappointing, is I was kind of looking forward to seeing how an immortal creature like a dragon, who can already live for centuries, could wind up becoming an Auspice. Not to mention the fact that having one of the Four Lords be a snake is kind of a cheat in itself; while Genbu occasionally has serpentine aspects (he's often depicted as a turtle with a serpent for a tail, or entwined with a serpent), as far as I know Seiryu has always unquestionably been a dragon.

I won't deny, though, that the character model for Seiryu looks pretty cool!
