PCs are close to Winterhaven when wolves attack.
They fight their way through them to Treona’s tower.
Treona tells them how Winterhaven was over-run by goblins a number of years ago, who renamed it Gorizbadd. She asks the PCs to recover a “slaying stone”… the last of a number of deadly artifacts that can only be used in and around Winterhaven as a weapon to kill nearly anybody / thing. Only way the slaying stone can be destroyed is by Treona’s ritual, or by using it.
Promises to give Sora some information on the one he seeks in exchange for help, and has asked Idria to locate some documents/scrolls in the library of Winterhaven (or Kindling Shop, as Jarr calls it). Also has agreed to pay the group 400 gold should they succeed in returning / destroying the slaying stone.
