Lassic's Castle is a dungeon in Phantasy Star. A special item is required to be able to see the castle, and even more to reach it. Only the strongest will survive encounters with the many strong enemies guarding its passages, but Alis must reach the room at the end of the dungeon if she is to face King Lassic and avenge the death of her brother.
