This Irish lass emigrated to the United States to escape her destiny as the protector of the Order of Druids in Ireland. Taking on the name Phoenix, this former professional Riverdancer romanced Piotr Rasputin and was the only original character serving as one of the X-Men on the game. I love the name Siobhan (pronounced Sh'van in many cases). Conneff was chosen for her last name in homage of Kevin Conneff of the Chieftains.
In this image, I particularly like her eyes and mouth (sorry you can't see it much under the watermark). Her hair is also interesting because I don't often draw curly hair (it's very difficult). I also like the phoenix pendant around her neck. I think this is based on a picture of someone, but other than the character of Amania from Robin Wood's People of Pern, I can't imagine who it could be.
