Do you remember the one-roll generators I posted a while back (I’m going to list some links in the first comment down below)?
After watching the Oath of the Frozen King video that Matt Click posted yesterday I applied the method he used but instead of just noting the die type I recorded the result as well and used my own Dungeon Generator to tell me about the dungeon.
d4 = 4: Entrance is hidden, guarded and magically locked
d6 = 2: Its purpose is a tomb or crypt
d8 = 6: It was built by a religious order or cult
d10= 3: What’s worth finding here is evidence about what’s really going on
d12 = 7: Movement is treacherous or difficult because of webs, ice, etc. (I’m going to go with ice as homage to Oath of the Frozen King)
d20 = 13: There is evidence of battle everywhere.
Now, from a purely world building POV (because that’s my bag) I appplied to same results to my other 3 one-roll tables:
Unique Monster in the Dungeon: The unique monster is a huge, tough, leathery twisted experiment adept at defending itself whose instinct is to take or steal (something to free it perhaps???)
An NPC you might encounter here will support you and is lawful. He/she is a ranger from the same town that you are from and found this place while out tracking and hunting something to hone his/her skills. This person also knows where it (whatever it is) is hidden.
Region = The tomb is in Perilous Mountains full of undead where a plague originated. There’s a unique, magical fruit and an unblemished well somewhere in the region at the center of a ruined town.
Applying your who’s, what’s and why’s can create something really unique and give you a dungeon ready to run.
EDIT: Should I include stuff like this in my Session Zero zine?
