Lost mine of phandelver
Gundren Rockseeker is a dwarven business man, his business interests are many and varied but recently involve an unknown source of potential revenue near Phandalin. Working with his brothers Tharden and Nundro, and a veteran warrior named Sildar Hallwinter, Gundren decided to recruit help from Neverwinter.
Gundren Rockseeker invited the group to be responsible for escorting a wagon full of provisions to the town of Phandalin, keeping it safe from the bandits along the road. Not letting on any further details about what his newest opportunity might by, the dwarf and his escort Sildar rode on ahead to prepare things in advance.
Gundren went missing shortly after hiring the adventurers, having been ambushed en-route to Phandalin by the Cragmaw goblins.
