For 7th to 10th level characters.
Below Whulmthar's ruined keep lies a crypt as old as the frost giant clan itself. After his slaying of the Steel Council and his bloody rise to power, Whulmthar ordered the crypt's expansion to hold the new corpses he had left in his wake. His brother Sydyr, who tried to oppose his sibling's savage coup, was ordered to dig the graves as punishment. Bound in iron chains inscribed with runic magic, Sydyr was forced to dig grave after grave, eventually hollowing out a cavernous hole in the earth. The keep fell shortly after his own death and that of his king brother in the many years that came, though his punishment continues. He hit bedrock centuries ago. His decayed, stinking remains ceaselessly slam his shovel against stone in a futile effort to dig deeper. His ears are filled with the ringing clangs of his work and the jeering taunts of the ghosts of Whulmthar's allies. He has forgotten who he was or why he suffers. He knows now only anger, pain, and the secrets of the Whulmthar Crypt.
