Just the Tip
Long ago, soldiers from Nerath built a strong fortress over the Shadowfell rift to protect it. The old keep lies in ruins now, and a new generation of cultists has secretly taken up residence here. They seek to undo the magical wards sealing the Shadowfell rift and open the way for undead horrors.
Update: The cultists led by Kalarel were defeated by Just The Tip, and Lord Padraig is in the process of contacting the cities to the south about sending a garrison of troops and engineers to rebuild the Keep and make sure the rift stays closed.
