L2Mafia operates seasonal x1000 PvP worlds built around Interlude gameplay. The official site distinguishes its Oldschool world on an Interlude client from Inferno, an Interlude Remastered world on a Classic client. Their seasons and systems should be read separately.

The Oldschool presentation describes staged equipment access, autofarm, events, raids and a player marketplace. Inferno documents free class changes, hourly raids, several in-game currencies and a revised Olympiad reward system. Both emphasize character progression through combat and events, but each world has its own opening and roadmap.
