Seven Sisters (Forgotten Realms)
The Seven Sisters—fictional characters of the "Forgotten Realms" campaign setting of the "Dungeons & Dragons" Role Playing Game. The sisters are epic level characters (characters possessing nearly super-human levels of skill and power) of differing abilities, most of which involve some form of spellcasting and use of magic. Created by Ed Greenwood, they have been featured in multiple novels, games, and officially created scenarios by an equally large number of authors/game-designers.
Forgotten Realms
Although the Realms were yet to be an official campaign world, the module "H1: Bloodstone Pass", released in 1985 by TSR, is now considered to be a part of the Forgotten Realms, although it wasn't until module H3 "The Bloodstone Wars" was released that Forgotten Realms became the official setting for the module series. The first official Forgotten Realms product was Douglas Niles's "Darkwalker on Moonshae", the first book in "The Moonshae Trilogy", which predates the "Forgotten Realms Campaign Set" by one month.
