The line comes from StarCraft, Blizzard's 1998 real-time strategy game, where Zealots are the Protoss warrior caste and Adun is their revered ancient hero. In the original game and the 2017 Remastered edition, selecting or commanding a Zealot can trigger this short battle cry. It later spread through StarCraft gameplay videos, strategy guides and soundboards, where fans reused it as a shorthand for Protoss pride and reckless bravery. Its brevity and recognisable delivery keep it useful for editors who want instant, old-school strategy-game flavour without a longer quote.
