Gundren Rockseeker

Gundren unintentionallyformed the Gruma Group by hiring Gruma, Esran Oakenheath and Ottar to odeliver provisions and supplies to the town of Phandalin, having come across a map hinting at the location of a secret and abandoned mine, The Lost Mine of Phandelver.

It appears that Gundren and his two brothers, Nundro and Tharden were working together to locate and claim the mine.

However, due to his knowledge of the location of the mine, he was kidnapped by or on behalf of The Black Spider or Glasstaff, resulting in his torture and ultimately death at the hands of King Grol in Cragmaw Castle.

Gundren had refused to talk to his torturers, but eventually yielded that key to the map [to the mine] was in his head. it is possible that Grol took this quite literally at first, resulting in Gundren's scalp being lifted akin to a saucepan lid.

A translucent jellyfish-like creature, summoned somehow from or on behalf of The Returner, was used to try and get information on the location of the mine as well.

Ottar and Gruma bury Gundren in Phandalin.
