Ayala is a character you're bound to recognise from the rest of the artwork, she's also one of my two primary characters from our NWN game sessions and longest running/best developed.

She's an Eronian Leonal, a form of Guardinal (Form of Celestial native to Elysium found in several D&D campaign settings), who works as Arbiter to Bahamut.

The model is an original I created, which later got added to the CEP2 (An unofficial expansion), and so many players have seen her model without realising =p

You can download the original model from here:
