Aberrant Dungeon

Board

The premier modular megadungeon board for adventures against aberrations.  This set is designed to allow you to quickly segment together an awesome adventure in a deep dark dungeon, full of eldritch abominations, gooey aberrations, consuming ruins, and weird science.

This is a modular board has its fundamental “room” on a grid of 8x8x5, but the smallest building block that exists here is 2x2x5, so each chamber is standardized to segment together, as long as you connect properly.  Above the ground level where all the modular tiles exist is a plain terrain building area, so that you can build up (or down) as needed.  You can use darkness or preplaced hide volumes to occlude the ground level.  Chambers are organized into strips with named waypoint:

8×8 Standardized rooms and hallways are the intended core of the experience, since they are the simplest to slot together.

8×16+ Standardized large rooms and hallways, which will still evenly slot in with lots of 8×8 rooms, as they are built in increments of 8 tiles.

Irregular rooms and hallways, if you want to break up the monotony of standardized rooms.  I think a mix is best, as it keeps it difficult for the players to predict paths, as well as make the design feel more lived-in.

Small rooms, hallways, fragments, and filler pieces to tuck in as you wish, or build out larger rooms from walls, corners, floors, and pillars.

Oversized “centerpierce” hallways and chambers are a good place to end a session, as your players explore your horror megadungeon.

Within the different chamber sizes, there are five core themes at work:

Overgrown Aberration:  This theme is the most common, using primarily Aberration tiles and props, with a general theme of overgrown tumors, tentacles, entombment, goop, pupae, and mysterious magic.

Cyclopean Geometry:  Smooth halls and weird angles lead to bizarre altars, impossible artifacts, and waterfalls of flesh.

Weird Science:  Strange contraptions that run on a mix of blood sacrifice, black magic, alchemical whirligigs, steam power, and a bit of electricity, the weird science rooms are the most “sci-fi” and may be fit for a nonmedieval campaign, or else a fantasy campaign willing to dip toes into the gonzo pool.

Repurposed Ruins:  Crumbling castles, extinct temples, or otherwise repurposed masonry is mixed in with other themes, but in some chambers that is the entire theme.  Perhaps a shrine to a river goddess has now been turned into a breeding ground for spinal parasites.

Natural Caves:  In my campaigns, and I bet in yours, a fair bit of natural cavediving takes place, so the natural pieces are meant to bridge between chambers where the aberrations house themselves, or else where the aberrations have not developed—or simply the border between the normal mortal world and the aberrations’ home.

I did not use any other creations here from TalesTavern, although I was originally inspired by Imp’s Gravewood Crypt and the many summoning circles out there, such as those by BiBo or tokoyamig.
