The Abyss: Dungeons Are Hell, but I'm Even Darker

Deep within the Abyss archives, a classified file marks the emergence of a player who defies all understanding. Codenamed "Wujian Guiyu" — the Endless Ghost Prison — this entity possesses abilities that have sent shockwaves through the system. Their Ghost Shadow ability renders them nearly invisible to the naked eye, appearing as nothing more than an ordinary human silhouette. Their second ability, a domain of unknown scope, exerts influence so profound that even the archives struggle to document its full extent. With additional abilities still unrecorded and a threat level that cannot be assessed, the file bears only warnings: retreat immediately upon encountering this player in reality, and if they appear within an Abyss dungeon, pray for mercy — for both yourself and the dungeon itself. The final verdict is absolute: impossible to contact, impossible to assess, impossible to counter, and utterly unsolvable.
