Olaf's name derives from Old West Norse ᚬᛚᛅᚠᛦ Óláfʀ, from Archaic Norse*Anulaibaʀ; meaning "ancestor's heirloom/descendant"; cognate with Old English Ǣlāf~Anlāf (hypothetical modern English: *Eam's Lave).
Many Vikings, Norse-Gaels, and Varangians bore this name and its derivatives.
His title means "bear-sark", referencing the garment worn by Norse berserkers.
Since his lore-retconning, Olaf fears his prophesied death in peace & obscurity and instead longs for an unforgettable, glorious death in combat, inspired by the common Indo-European literary motif "Imperishable Glory".
