The 'Seteth Says' meme originates from the 2019 tactical RPG Fire Emblem: Three Houses, specifically centered on the character Seteth, the stern second-in-command of the Church of Seiros. It gained traction on Twitter and Reddit shortly after the game's release, often utilizing a specific portrait of Seteth accompanied by a dialogue text box. The meme typically parodies his voice actor Mark Whitten's delivery, featuring Seteth making increasingly absurd 'requests' to the students of Garreg Mach or commenting on internet trends with his characteristic gravitas. It remains a staple of the Fire Emblem community for its versatility in addressing everything from gameplay frustrations to niche pop culture references.
