Gundren Rockseeker

Gundren Rockseeker is a dwarven business owner who has appeared in both the Velmaverse continuity and the Shmexiverse continuity due to being the introductory character for the 5th edition starter adventure 'Lost Mine of Phandelver' campaign.
In the Velmaverse continuity he first appeared in the campaign Lost Mine of Phandelver during the first session, where he met with the trio: Skeldar, Gogdor, and Omniscidor at the inn called Hekburn's Arms in Neverwinter and tasked them with escorting a wagon full of supplies to the nearby town of Phandalin, in exchange for 10 gold pieces. He explained that he and his brothers had found something amazing and he needed to ensure its safety, but would also require that the wagon go ahead a few hours before the dwarf and his fellow adventurer Sildar Hallwinter would set off. After his capture by the goblins he was taken to Cragmaw Castle, where he would be freed by the OG's soon after during the Cragmaw Castle Altercation.
In the Shmexiverse continuity, following the main story of 'The Lost Mines Of Phandelver' the party was leading a cart for the dwarf Gundren Rockseeker, when they found a dead horse with a black feathered arrow in its side in the middle of the road. As they inspected the dead animal they were ambushed by a group of goblins, fighting off the group and following the final goblin into the main hideout of the goblins they fought through its many rooms and following the story as presented in the book.
