The largest of the three western lakes near Hagswood, Sethlund has become hag territory. The coven uses its waters for rituals, its shores for camps, and its depths for disposing of victims. Fishing boats haven't worked these waters in decades.
The lake's surface often carries an oily sheen—residue from hag magic or something fouler. Locals claim the water itself has become poisonous, that anyone who drinks it falls under the hags' influence. True or not, no one tests the theory voluntarily.
