A Chronicle of the Dragon Guard
Played by "unknown" at this time
The Shadow Dragon lives in the Underdark (possibly directly below where we are living).
(This information was gained during one of our chats with the ninja Black Wind.)
At some point in the past, the Shadow Dragon moved into the Underdark and took control of one of the Drow Houses. He has also removed them from the service of their Spider Goddess. All of this is much to the consternation of the other Drow Houses.
