The Vrykul are a warrior race from World of Warcraft, introduced in the Wrath of the Lich King expansion as the ancient, viking-like ancestors of humans in the frozen land of Northrend. Their deep, aggressive voices became part of the game's atmosphere in quests and battles across that region. Clips of their shouts later spread through fan soundboards and gaming edits, where players reuse them outside the game. The sound endures because it instantly signals a brutal, old-world warrior without needing any dialogue or context.
