Blueflame ghost

Blueflame ghosts are spirits of members of the adventuring group The Nine which are imprisoned within magic items. The term comes from the magical blue flames that surround the ghosts.

Three Blueflame ghosts are known to exist. Treth Halonter and Relve Langral are trapped within the Wyverntongue Chalice and Flying Blade  and a third was briefly summoned in a melee during the Dragon Council in 1479 DR although the identity of the third Blueflame ghost is unknown.

The owner of the item containing a Blueflame ghost may call the spirit forth and force it to do his bidding which is usually to kill someone. As of 1479 DR, Marlin Stormserpent, a servant of Manshoon, possessed the Wyverntongue Chalice and the Flying Blade.
