The Three Hags of Telzyn have come down from their northern misty lakeside to spread and evil sickness upon the great Sarthmarch forest. Setting up in the great and ancient Sarthiel treasury, long abandoned by elvenkind, they have begun to spread a cursed sickness upon the land. Along the way they have attracted many terrible creatures, not the least of which an greedy young green dragon looking to make a lair for himself. A gnome cleric of Saint Dyfed has broken the taboo of interference with elven matters and taken it upon himself to find a way to cure the sickness. It did not go so well for him and he has been captured by the dark fey infesting the ruins.
