Coran and the Wolfweres

In the northeast part of the Forest of Tethir, Coran will ask you to help him resuce Safana who has been captured by wolfweres.
Go to the Wolfwere camp to the east which is marked on your map. You will learn that Safana is in league with Lanfear, the leader of the wolfweres and that she had set a trap for you.
Lanfear will kill Safana and then attack Coran and your party. Once the wolfweres have been defeated, Coran will leave to drown his sorrows if he survived the battle.
