One-page dungeons are perfect for dropping into a campaign or as a one-off game. To a Kobold is a one-page dungeon, from Fortiter Games. It details the lair of a band of kobolds who have been raiding local merchants. Provided, on a single sheet of A4-sized paper (although easily printable on Letter-sized paper), is a keyed map of the lair with brief room descriptions. Also included is a 300dpi JPG of the unkeyed map for use in VTT applications.
I have written To a Kobold with the 5th edition of the world's most famous fantasy role playing game in mind. However, you can use it for any fantasy RPG with minimal work.
As this first one-page dungeon from Fortiter Games has been released on Burns Night there is a slight nod to the great poet himself, Rabbie Burns:
"Wee, sleekit, cowran, tim'rous beastie,
O, what a panic's in thy breastie!
Thou need na start awa sae hasty,
Wi' bickering brattle!
I wad be laith to rin an' chase thee,
Wi' murd'ring pattle!"
To a Mouse, Robert Burns
