The line comes from Dark Souls III, released in 2016, where Siegward of Catarina is an honour-bound knight who promised to help his old friend Yhorm the Giant. If players complete Siegward's quest, he joins them for the battle against Yhorm in the Profaned Capital, making the greeting a payoff for a long, wandering storyline rather than a throwaway line. Fans still reuse the short clip in edits and tributes because it distils that loyalty and tragedy into just a couple of seconds.
