Modolf was one of six sons born to Hemdall and Heulyn. He was progenitor of Clan Drummond, who was granted mastery over the isle of Undvik, unlike his brothers displayed no extraordinary abilities: he was neither wise nor especially brave, nor did he possess any particular gift which would make him a great individual. He resented Hemdall for not bestowing greater talent upon him. Hemdall, however, insisted he had blessed each of his sons with equal gifts, but not all revealed themselves at once - Modolf would have to wait for the right moment for his gifts to step forward. Yet the hero was impatient and could not wait for this moment. Instead, again and again he sought out trouble of the worst sort, hoping each time his hidden talent would shine. Hemdall grew angry with his son and decided to bury his gift even deeper. Modolf died after a long and unruly life filled with incredible adventures, but a life during which he never discovered his talent. His descendants decided to continue his search elsewhere. They abandoned Undvik and invaded Ard Skellig, eventually taking half of that isle for themselves. They now seek to take the other half, but whether doing so would finally reveal their line's unique gift – no one knows.
His brothers are Broddr, Grymmdjarr, Otkell, Sove and Tyr.
