Deckard Cain first appeared in Diablo in 1996 as the last Horadrim scholar in Tristram, and his greeting became one of the most quoted NPC lines in gaming. Players heard it repeatedly while identifying items and learning the story, so it turned into shorthand for nostalgia and exposition. Clips and remixes spread across forums, YouTube, and Twitch in the 2000s and 2010s, and the phrase now appears far beyond Diablo as a meme cue whenever someone settles in to explain something at length.
