The Sisterhood of the Sightless Eye are a closely organised guild of women sometimes referred to as rogues and are highly skilled archers. Their home is located in a monastery in Entsteig guarding the pass between the Western Kingdoms and the East, and the Aranoch desert.
Background
The sisterhood is shrouded in mystery amongst the local people, and not very much is known about the organisation. The sisters employ a religious/military structure and is at least to some extent interested in gathering monetary riches, although this might be the goal of individual sisters rather than the sisterhood itself.
Known only as wandering Rogues in the West, the Sisters conceal their secret affiliation by posing as simple travelers. Many pompous fools have made the mistake of underestimating these steel nerved women in combat and paid a terrible price for their vanity.
The sisters are not only located in the West, as there are sisters as far away as the "Eastern dunes" (Aranoch?) [1]
