Ulme is the village bard within Halvar's Viking crew. He strums a harp and performs musical compositions during voyages to entertain his fellow Vikings. His poetic nature and artistic inclinations soften the crew's rugged life, though his performances often go underappreciated. Despite this, he remains dedicated to lifting morale as their entertainer.

Beyond music, Ulme serves as the chief cook aboard Halvar's ship, handling food preparation during expeditions. He discovered Vicky stowed away in a barrel on one voyage, leading to her assisting him in the kitchen. This role blends practical duties with his artistic side.

Ulme reveals unexpected capabilities beyond his primary occupations. He excels at long-distance running, earning him selection for a marathon competition. His literacy and talent for improvisational poetry and acting prove strategically valuable; an impromptu poetic performance successfully deceived adversaries. These hidden skills mark him as one of the crew's more intellectually capable members.

His gentle disposition balances with active participation in the crew's combative endeavors. Though not naturally aggressive, Ulme fights alongside his fellow Vikings when necessary. He also acts as a mediator and contributes to group problem-solving, integrating him into the crew's dynamics despite diverging from traditional Viking behavioral norms.
