From publisher blurb:
Populating the dungeon is easy, right? You flip open a book of monsters, select a creature, and toss it behind the next door just as the adventurers are about to bash it down and continue their quest for treasure. At least, that’s one – very valid, in my opinion – way to approach stocking the dungeon with inhabitants.
Or, if you wish, you can take a different approach and make each monster found in the dungeon a little more than the speedbump between the heroes and their ultimate goal: finding more treasure!
A Dozen Dungeon Denizens details twelve monsters that are ready to join the more generic beasties in your next dungeon design. While a systemless work – like all of the entries in the A Dozen . . . series – this PDF includes more than just the name and description of a monster. The twelve monsters offered in this short work may be used as encounter seeds, with each entry existing for a single reason: to inspire you, the gamemaster!
A few of the twelve include a smattering of history, telling how the monster may have ended up in the dungeon, what it might be looking for in life, as well as how it will react to the party and what treasures (if any) it may have that the adventurers will no doubt wish to take.
Additionally, I have written a brief rumor about each of the monsters that may be used when the PCs are visiting a tavern or inn. They may overhear one of these rumors or, maybe, when asking around, one of the locals shares just the right piece of gossip that sends the party into the nearby dungeons.
