Glamrig was a rock former of the Windholme dwarven and an old warrior who had fought in the war of six nations and the old human wars. His hand to hand acumen was only exceeded by his skills with the axe, which he had swung on so many battlefields. Even Isgrimm, the mightiest rock former, member of the circle and the master of Mulandir was envious of his abilities. As the more morbid motives of the circle became known, Glamrig turned against Isgrimm and trapped the betrayer the dwarves' knowledge at his tower near Windholme. The dwarves fought each other for two days until Isgrimm defeated Glamrig. In revenge for Glamrig's resistance, Isgrimm forged his soul to a Rune, so that his former enemy should now serve as his protection.

The ghost of Glamrig's brother, Gurim, explained to the rune warrior, that he had once sought for a way to break Glamrig's rune enslavement.
Laurin promised Gurim to help him if he would slay the four enemies of Laurin: The dragons Sheeha, Andar, Zandarh and Iridon. Gurim did so but Laurin tricked Gurim and kill him while keeping Glamrig's rune for himself. After the rune warrior summoned Laurin and killed him, Glamrig's rune then came into posession of the rune warrior and thus received a new master.
