Thorim is a titan keeper encountered in the Ulduar raid in World of Warcraft, introduced with the Wrath of the Lich King era. During his story he recognises the player with the line about remembering them in the mountains, and players began quoting the slow, portentous delivery out of context. Repeated in forums, videos and raid chat, it became a shorthand in joke among Warcraft players. It survives as a nostalgic meme sound because the phrasing is instantly quotable and works far beyond its original boss encounter.
