Hordes of the Underdark Characters

GameSpy has posted an article that explores the different customization options BioWare is adding to characters in Hordes of the Underdark, including robes, wings and tails, portraits, and more. A snippet:
Since Hordes of the Underdark has your character start off at level 15, it's safe to assume your character will have some sort of history -- whether it was taking that character through the original Neverwinter Nights or the Shadows of Undrentide expansion. As part of the new "Customize Character" screen, you'll be able to modify your character's biography.

On the Customize Character screen, you'll also be able to modify your character's appearance (for example, choose one of the many new heads in the expansion) and its portrait!
