No one knows what happened to Skaravojen when she was trapped in the sea, but the next time this magic beast is sighted, she is attacking the dwarf wardens in the Dreadhold deep in the Lhazzar Principalities. How and why she got there was a mystery, and what she will discover is one of Karrnath's biggest secrets...
As I promised earlier on Gleemax, here's a portrait of Erandis d'Vol the Lich Queen of Eberron.
I owe the completion of this art to the great amount of input from Gleemax Eberron forums, including the always inspiring comments from Keith Baker, and also to the original Vol's portrait in 4th edition Eberron Campaign Guide (you can see a revised version of that funny hat), as well as the art from Wamusato (see http://www.pixiv.net/member_illust.php?mode=medium&illust_id=1491893).
This is, as I envision, Vol's appearance at the time she embraced lichdom. As Keith has mentioned, her aging should have stopped at that point, when her appearance was equivalent to a teenage human, and it is not surprising that she has disguise spells functional 24-7, which can very reasonably be used to assume the appearance at the time of her *death*.
Gruden's prison break indeed succeeded, and while he is setting up fire in Flamekeep's backyard, undead armies emerge from the waters surrounding Thronehold Island and strike Thrane flat-footed.
