Details and conjecture relevant to the Ultimate Sandbox
  • The book begins with a sample cross-section of a dungeon, as shown below. I plan on placing this dungeon somewhere not far from the City of Greyhawk.


  • Later on a sample level is included. It's more of a way to demonstrate various tricks and traps than a genuine level, but I'm going to include it as part of one of the dungeon above. The level in question needs a chute and a slanting passage, which doesn't match anything in the sample, so it'll have to be one of the levels below 6th (the cavern). The map for this area is below:


  • There's a sample of play that features some adventurers (including an elf and a magic-user who can cast hold portal) exploring a dungeon and fighting some gnolls. I've mapped out the dungeon described as shown below. These adventurers will be dead bodies deeper into the dungeon, and found with them will be their gnoll treasure: 2,000 copper pieces, an onyx case worth 1,000 gp, a jeweled necklace worth 5,000 gp, and a pair of elven boots.


  • It's noted that Greyhawk Castle has "over a dozen levels in succession downwards, and more than that branching from these, and not less than two new levels under construction at any given time. These levels contain such things as a museum from another age, an underground lake, a series of caverns filled with giant fungi, a bowling alley for 20' high giants, an arena of evil, crypts, and so on".
  • There are some rules that I plan to apply only as special circumstances for "megadungeons": doors are usually stuck for PCs, but will always open for monsters; the dungeon layout may change between visits; monsters all have infravision, but will not benefit from it if serving a PC. Mythic megadungeons such as Blackmoor or Castle Greyhawk are actively hostile towards the PCs.
  • Blackmoor is described as "a village of small size (a one-horse town)".
  • The City of Greyhawk (written as "Grayhawk" here, but we all know better) is a large city. It's said to have bazaars, inns, taverns, shops, temples, and a risky Thieves' Quarter.
  • The board from Outdoor Survival was used in the original Greyhawk campaign for wilderness exploration.  I'll be using it in the Ultimate Sandbox as a nearby wilderness area. Here it is below:


  • There must be a lot of unclaimed wilderness around Greyhawk, as PCs are free to clear areas out and build their own strongholds. The region is also dotted with small castles ruled by fickle NPCs. The Outdoor Survival map is about 215 miles (43 hexes) x 210 miles (42 hexes), and it contains (I think) 18 different castles. Anyone in charge of a castle is considered to have their own barony, and can start collecting taxes, but they also seem to be pretty autonomous. I guess that there is a ruling authority around Greyhawk that governs these things and hands out baronies, but that they're fairly hands off unless someone starts causing them too much trouble.
  • Based on the wilderness wandering monster tables, there must be somewhere in the campaign setting a "lost world" swamp or jungle that's full of dinosaurs, and a mountain range inhabited by prehistoric mammals.
  • There are many references to Barsoom, the setting of Edgar Rice Burroughs' John Carter novels, so there should be some way of getting there in the campaign.
  • Sages won't work for clerics or magic-users, which I'm going to chalk up to some sort of guild rivalry or professional jealousy.
  • Vikings are mentioned. I won't have actual Vikings in the campaign, but there should be some sort of equivalent.
  • Apparently orcs are readily available to be hired as men-at-arms by chaotic character.
  • It's noted that ships might sail off the edge of the world. Is the World of Greyhawk flat? I'm not altogether opposed to the idea.
