Bioware just released a trailer for the upcoming DLC for Dragon Age II, Mark of the Assassin, to be released on October the 11th .

The DLC features a "new" companion character named Tallis, that is no one else than the protagonist of the web series Dragon Age: Redemption, played by the charming Felicia Day (star of Buffy and The Guild, between other things), that did the voice acting for the DLC as well.

Unfortunately, the in-game Tallis doesn't look nearly as beautiful as Ms. Day (some modding will be required to do her justice, I guess). But you can still enjoy the trailer past the cut:
