Player's Guide to Mirrorrim - Preview Edition (5E)

This preview contains player-focused teasers for the setting, but a creative game master could use what is here to build their own campaign and dungeons. Much of the content is system-agnostic, but the racial options are OGL 5.0-compatible. 

MIRRORRIM is a huge, ancient desert city-state built on top of a megadungeon.

Mirrorrim contains thousands of years of secrets and wonders, buried beneath the city streets in sealed-off caverns and tunnels—the city’s “megadungeon.” As dungeon explorers, you’re in grave danger. First and foremost, the city’s government forbids you to enter this dungeon. After that, you’re in danger from the monsters and traps that fill the dungeon’s halls. (And fear of those monsters escaping is why the city forbids you from tampering with the dungeon.)

Inside the book, you'll find 57 pages of content focusing on the setting and character-generation options:

Races

Some of the best stuff in here lies in the unique takes on races, even the usually-familiar ones. 

Elves live less than 30 years and make pilgrimages to the Great Tree to store and retrieve racial memories. Dwarves are literally made of stone. Gnomes see into the spirit world. Halflings are a survivor slave race who have evolved to eat less, take up less space. 

You can play Djinni: air elementals enslaved to a magic lamp. Or mean-spirited Efrit fire elementals. Gnolls are PC races, and they're shrewd, socially clever "pack" people who function well in cities. Ratlings are small rat humanoids, surprisingly well cultured and impeccably dressed.

Want really weird? Gargoyles are living statues from a local neighborhood, who have come to life, but still feel a pull to that part of the city. Flamenku are flamingo kenku from the desert who get their nutrition from a weird, blue algae.

Even humans come in two varieties in Mirrorrim: Commoner and Noble.
