When your players insist that they want to delve deeper than the dungeon they have reached the bottom of, there will be one or two passages they can follow. Here’s what they find when they descend:

Draw a card. The value represents the nature of the section. The suit represents the threat and obstacle.

A – PALLID PAMPAS-GRASS CAVERNS – the head-height grass covers the floor of the cavern; it takes effort to push through and is very difficult to do at speed without passing passive STR checks

K – TRYPOPHOBIC SINKHOLES – the surfaces of these caverns are split with holes of various size and depth; sometimes these sinkholes lead to lower caverns, though often there will be something aggressive hidden within

Q – GARGANTUAN BADGER SETT – the walls have definitely been carved out by the claws of an enormous beast; passages turn and jut at strange angles and often end abruptly

J – DOLERITE SPUR NETWORK – much of these caverns are open expanses, pierced with thick trunks of igneos rock; the surfaces are smooth but not slippery, however moving between spurs unaided requires passive DEX checks to avoid falling

10 – FOSSILWOOD CLADDING – the surfaces here are paved and the network appears to have been constructed; the walls are clad in wood panelling that has fossilised over time; some of the surfaces depict unknowable things

9 – SKELETAL CATHEDRAL – the earth is held back by the enormous ribs of an animal that has long since rotted away; some of the bones are broken and it seems that you can follow the passage afforded by their being empty of marrow

8 – DEEPWEAVE FABRIC – the walls of this area appear to be a fine weave of a fabric you cannot quite identify; if the walls are cut into, the fabric continues to significant depth

7 – DESSICATED LYMPH – the veins through the rock here seem to retain traces of organic matter, but the lymph has long dried away; the passages bulge and narrow at seeming random

6 – KERATIN CANYON – the sheer surfaces of the canyons here thrust high with the fibrous rigidity of nail and hair; sometimes a successful passive INT check will reveal weak-points in the growth

5 – FOLDS OF LEATHER – observed from a distance, the deep valleys in this section seem to take on the appearance of cracks in leather; up close, the rough surfaces of the valley walls are difficult to classify

4 – STONEPULP HONEYCOMB – the haphazard construction in this section show unmistakable signs of having been chewed and spat out, like the paper of a wasps’ nest

3 – SUBMERGED SPIRALS – the interlocking shells in this section split out from each other at all angles; a third of all areas are flooded with a translucent milky fluid

2 – CARDED ALLOYWOOL – the surfaces in this section are covered in fibers of metal loosely twisted together, giving to pressure but impossible to part; progressing through these floors require passive CON checks to avoid becoming fatigued

The suit of the card drawn will represent the potential threat in this area:

♠️ – hostile native fauna: perhaps of animal intelligence, perhaps monstrous humanoids

♥️ – toxic environment: perhaps poisonous gas, perhaps sharding surfaces

♣️ – physical obstruction: perhaps natural cave-ins, perhaps extreme distances

♦️ – being hunted: perhaps intelligent pursuant, perhaps natural predation

Going yet further underground its been reported that some of these section appearances can become combined.
