Under Chagrinspire

Sequel to d100 Underground entrances

This deals with underground passage types you can discover

Tunnels and passages are everywhere under Chagrinspire, sometimes overlapping or connecting. Each has its own character.

There are three great caverns under Chagrinspire almost a kilometre tall. 
One has a great grey gnome city of Gloomheim the greatest underland trade city of the underland. The Black Sphere gnomes came from here but are a minority faction.  

The second is a vast mushroom forest crawling with fell faerie and goblinoid folk and creepy crawling giant vermin. 

The third is a vast garbage dump with a kingdom of dumped automatons, beast folk tribes and worm cultists. There is also a ruined city of the old ones here back to the dawn age and used by the monster kings in the age of darkness and then necromances. The Black Sphere sealed the old ones city off and only allowed approved researchers inside not cultists. 

Black Sphere flesh golems
Weild a steel short spear and all others within 120 range are mindlinked in unison and pool and share HP. They are brutal destroyers and many become increasingly deranged so are sent to the front lines to be a river of mayhem and murder. When out of control they swarm in a group mind vs any other moving thing not in the group. When "killed" body parts will still twitch and move and can be recycled for new golems or seed new clones. Some compare these horrors with the stupidity of troll ancients breeding a regenerating war troll that replaced the old troll civilisation with chaos. New ones will obey Black Sphere commanders they trained with. The longer they live the more they revolt. They don't talk but understand orders. It's unclear if they feel, care, or think when created   

d12 Tunnel Types
1 Natural cavern tunnels lead to the great caverns under Chagrinspire decorated with prophetic cave art waning of the coming of the Black Sphere

2 Ancient burrows of living creatures giant worms, land sharks, mega bugs, kaiju and colossal beasts. Can be risky and random but often link to long-buried ruins or the deep caverns. They say trolls gnawed these passages in the earth like worms early in creation

3 Ancient dwarven underground highways, very straight, dug in the middle dawn age before modern humans existed, geometric designs with vast statues of forgotten dwarven gods and heroes. Side passages link to the greater caves under the wasteland. Underland traders use these to cross the continent and trade hidden from humans

4 Monster Kingdom underground highways, tunnelled to enemies to occupy them even underseas to link them to their slaver city buried by Shadelport today to other continents or under hazards like mountains. Many of these crawl with monsters, traps and curses. Link to the greater caves under the wasteland. After the fall of the monster age of darkness, they were used by the necromancer era peoples leaving undead everywhere

5 Kobold Highway is a dungeon complex built of redbrick built by kobolds who bound evil s[irits here to worship and bring the dungeons to life. Kobolds often live at gateways and bunkers on the highway stops and goblins or abhumans might claim these tunnels. Many surface links to places kobolds use including kobold-operated train stations and bases for train gangs 

6 Flooded caves and ancient tunnels are common and include underground rivers and the vast underwater lakes in the deep. Aquatic beings especially fish and frog folk will occupy these with passages to Lake Vinigar on the surface or deep cave lakes. There may be air filed chambers and ruins only accessible by water breathers or amphibians  

7 Goblin-infested mines often link to industrial sites on the surface and the underground fungus caverns especially. They trade with kobolds and operate ancient mines abandoned by the Black Sphere. Many sections are abandoned but noises will carry vast distances  

8 Sewers and drains of the ancients often connect to rivers and wetlands and even some deep caverns. Sewerage-dwelling telepathic tentacled horrors charge a toll of corpses and excrement to pass. Rat and frog folk battle here and fish folk sometimes scout them. Effluent from alchemical factories on the Plateau and across the waste are toxic mutagens

9 Pneumatic Tube Line a metal circular tunnel system mostly not functional as rats ate all the seals. Metal tube trains were sucked and pushed to stations and the system was a late edition which failed. Rust-eating monsters love it here but they do like other metals. Automatons don't come here. Some lines are functional often connecting to a black sphere outpost, automaton centre or laboratory. Some now operate with a air elemental behind and a void elemental in the front as the tubes were too difficult to seal and make airtight

10 Service tunnels often near the surface with various pipes (water, steam, oil, message pods) and cables (for magical energy-feeding Chagrinspire). Small golem carts were used some 2-4 passengers with 1in6 pull d6 trailers each seating. Skating and kill cart kobolds love these areas but automatons and grey gnome sapper troops may use them also  
11 Automated freight train line tunnels - intruders are treated like a disease by machines
12 Chagrinspire passenger train rail line tunnels radiate across the wasteland
