Figured it was appropriate to transfer Io's concept drawings over today, February 8th is the closest approximation I have to her birthday, earth time. Not really sure how one would keep track of days for someone born on another planet with a different orbital period.
(Though I hope to see the day when there are official rules for this type of situation)

I might make an official ref sheet later and file this into the Characters category, details will have to wait until then.
