Editing Castle Greyhawk (section)

===The Tower of Magic===
Surface ruins. The surface ruins are mostly abandoned. They include a temple to Boccob, barracks, storerooms, mess halls, and guest quarters. A large band of kobolds currently dwells in the southern half of this ruin, and elves guard the entrance. During Castle Greyhawk's heyday, the Regalia of Neutrality were evidently stored in the Temple of Boccob here, and were the goal of countless pilgrimages. They are now gone, but something of their power still remains. This level is coded P100 in Greyhawk Ruins.

Zagig's Gauntlet (P200). This is a twisted maze designed by Zagig to vent his eccentricities, test the mettle of his apprentices, and guard the crypts below.

The Ochre Crypts (P300). This level contains the crypts of Zagig's apprentices and family members. Living as he did for hundreds of years, he outlived a lot of people. The stonework is a distinctive ochre hue. Expedition to the Ruins of Greyhawk removed the passageway that led to stairs from the surface ruins, connecting the crypts only to Zagig's Gauntlet.

Apprentice's Walk (P400). This level was originally built as dormitories for Zagig's apprentices. For a time this and many other of the levels beneath the Tower of Magic were used for an experiment conducted by the Ring of Five on the impact of magic on the three philosophies of evil. Staircase 2 in the surface ruins has evidently been changed in Expedition to the Ruins of Castle Greyhawk to lead here instead of to the Ochre Crypts, while staircase 4 on this level has evidently been changed to lead from either the surface ruins or Zagig's Gauntlet instead of from the crypts.

The Sanctum Arcanum (P500). This level is a complex of classrooms and laboratories.

The Vaults of Creation (P600). This level was intended for golem creation and research, but never finished. The map was changed extensively between Greyhawk Ruins and Expedition to the Ruins of Greyhawk, but a few of the rooms match up. P612 matches F12, P601 matches F11, and P602 matches F15, but the destinations of the staircases and tunnels leading from those rooms have been altered or blocked.

Master's Walk. These were Zagig's personal workshops and libraries.
