What would happen if Yuna had successfully summoned the Final Aeon? What if Auron had sacrificed himself to become Yunas new fayth?
You'd have Hades, of course!

Auron is no stranger to death, and so Hades felt like the most appropriate form for his spirit to take. The design didn't require much change, as both Auron and FF7/FF9 Hades have long, flowing red robes. I've played around with the designs a bit though, to make Auron seem more zombie-like; and even the Murasame has aged to a point of rusting (needs some colouring).
I later intend to add in skeletal wings, and the traditional patterning you'd expect to find on his fayth stone.

And I'm proud to announce I accidentally learned some new Corel Photo-Paint tricks that will save me hours of time in the future! Woo!
