The Covenant.

A tight knit group of hags, whose missing sisters have greatly diminished their strength. However, the remaining hags are not to be trifled with. It is said that, for a price, they can fulfill any of your darkest desires. Recently, the Gate Wardens returned one of the hags, Glenda the Grave Hag, to Castallian to be reunited once more with her Coven.
