Things I would like to do:
- a bundle of hamlet and village maps, with keys,
- an all-trap one-page dungeon, à la Tomb of Horrors,
- a set of megadungeon modules.
- use standard geomorphs in a tic-tac-toe pattern, with the special geomorph in one of the nine positions;
- map around the special geomorph using either the standard dice-based random dungeon tables or pure inspiration;
- use one of a set of unkeyed maps with a blank geomorph-sized square indicating placement for the special geomorph.
