Stuck on an idea for an adventure location, dungeon level, or what have you? Here's my Yuletide present for you: the SIX QUESTIONS TABLE.
Roll 3 d6 of different colors on this table for each adventure location. Let's call them white, black, and red.
The white die is something about the area that is generally known or easily found out.
The black die is something unknown about the area.
The red die is false information or appearance about the area, that hides a different reality.
Each number on the dice sends you to a row of this table, where another d6 is rolled; for the red die, roll twice on its row, the black die for the false reality and the white die for the true one.
A roll of 6 (except as HOW) always means "none of the above; invent your own."
1: WHO: a being that rules the area.
1 = Warlord; 2 = Wizard; 3 = Priest/cult; 4 = Monster; 5 = Extraplanar being
2. WHAT: a thing that defines the area.
1 = Treasure; 2 = Magic Item; 3 = Knowledge; 4 = Portal/Key/Map; 5 = Magic/Sacred Place
3. WHERE: special features throughout the area.
1 = Fire; 2 = Water; 3 = Natural/Rough; 4 = Worked/Elaborate; 5 = Plants/Growth
4. WHEN: roll again on the 6 Questions for something that was formerly true of the area. If you roll 4 again, use this table:
1 = Was a mine; 2 = Was a temple; 3 = Was a fortress; 4 = Was a settlement; 5 = Was a tomb.
5. WHY: the use of the area
1 = To imprison; 2 = To produce; 3 = To protect; 4 = To learn; 5 = To store
6. HOW: the working and nature of the area's perils
1 = By machinery; 2 = By magic; 3 = By nature; 4 = By brute force; 5 = By superhuman skill
Example: I roll a white 6 (HOW), black 4 (WHEN), red 1 (WHO).
My roll under the white HOW is "By machinery."
My re-roll for the black WHEN is 5: WHY, then 6. Creatively, I decide it was formerly used "to destroy."
The red, deceptive WHO die turns up a 4 - "monster" for appearances and a 3 - "priest/cult" for reality.
I decide that the legend of the place speaks of a giant monster, The Gnasher, who dwells in the middle of a vast cave system filled with perilous machinery. In reality, The Gnasher is the object of worship by a secretive cult of troglodytes left over from the place's former, unknown function as the wrecking yard of an advanced civilization. The trogs keep the machinery oiled and working.
