Gygax wrote about his experiences in this game in what would later be called "one of the foundations of our favorite hobby," by Dungeon magazine editor-in-chief, Erik Mona.
[3] In 2004 the adventure was updated to the 3.5 edition rules by Kuntz, Mona and James Jacobs (with some advisory material provided by Gygax), and re-titled "Maure Castle."
Each area includes its own challenge, ranging from images that come to life and attack to pools of dangerous fish to a climactic encounter with an iron golem.
The module involves a storehouse of magical traps, artifacts and other devices gathered by the architect of Maure Castle, known only as "Uncle".
The exact relationship and placement of Warlock's Walk relative to the other published levels of Maure Castle remains unknown.
As detailed in fragments Afelbain's Diary (in Dungeon #112, pages 88–89), the following additional levels exist below Maure Castle: 2nd The Retreat, 3rd Old Laboratories and Testing Chambers, 4th Dark Tunnels, 5th Old Dungeon, 6th Chambers of Antiquities, 7th The Statuary, 8th The Greater Halls, 9th The Family Crypts, 10th The Reliquary, 11th The Outer Sanctum, 12th The Treasury, 13th The Old Caves, 14th Elluvia's Pit, 15th Warlock's Walk, 16th The Cells, 17th The Furnaces, 18th Our Master's Level.
[2] Additional information about the Maure Castle dungeon levels is also revealed in James Jacobs' "Demonomicon of Iggwilv" article on Malcanthet in Dragon #353 (Elluvia's Pit is specifically mentioned).
[7] There are at least 8 portals to other planes as Expedition To The Ruins of Greyhawk states that the apprentices of the last Suel mage of power, Slerotin, left Oerth at Maure castle, each to their own personal demiplane.
Only one Octych has been discovered (in the ruins of Castle Greyhawk), and another lies in Dragotha's treasure hoard in Paizo's "Age of Worms" adventure "Into the Wormcrawl Fissure" (in Dungeon Magazine 134 [May 2006]), while the others remain lost.
