A smaller area, just 8 by 16, reached from the Vestibule and the Dungeon Entrance. Once again, only the outer area is immediately accessible. The centre can only be reached by teleport at D16 and there is a locked room past D1 which can be unlocked with a blue lockpick. In here, at E1, is a teleport to the Mausoleum on Level 3. A teleport from the Treasury leads to a locked room at C16.
You'll learn that the wizard came to Twinion and caused the volcano to erupt. His castle is buried deep in the bowels of the mountain. A troll cleric tells you someone left a rune on the floor which said that to reach the King's apartment you must take a turn for the worst. Another NPC tells you scrolls and amulets contain magic here but the magic in them is soon exhausted.
Once you have entered the centre section, you'll find four rooms, each with an encounter, some with very good treasure especially elf clerics and rogues at F9 and goblins with gold coins at F11. A teleport at C5 leads to the Basement in Level 2.
