Chagrinspires Secret Rail Network 1

Patreon: revision of vol 1 and 2 for chagrin spire books.
Vol 2 has 200+ room gatehouse done - its going well

Vol 3 has started - I'm working on the automaton class and will have mutant class and mutations for chagrinspire specifically. A quick guide to level one, especially the third segment and mote on the spire.

I have realised Chagrinspire is 16km tall so I'm happy for it to be seen from a distance
. It's a great place to launch a global airship empire from and possibly trips to the moon and raid the crystal citadels of the star people. I guess the kobolds living that height are more streamlined and barrel-chested. Jetliners would avoid it. Please suggest other consequences of this foolishness. How visible would it be from how far away? Can it be a continent-wide reference point? The axis mundi of entopy? 

------------------------

Under the wasteland, there is a vast network of tunnels. The tables in vol 1 d100 subterranean entrances. The Quick type table is good for the wasteland surface but in the deeps below Chagrinspire, there is a whole grey gnome city, a vast lake, a giant cave of garbage from the apocalypse war and a vast fungus forest of goblinoid civilisation.

The trains under the waste connect to the complex under Chagrinspire and there is a spiralling loop though the entirety of Chagrinspire into the stratosphere.

d12 Deep Tunnels 
1 Service Tubes 3m wide round pipe-like tunnels connecting apparatus for water, power, steam, mostly used for transit and vermin filled 

2 Freight Line 4m high 6m wide small cargo only smaller gauge freight line with some abandoned cars or golem engines and possibly some vermin. Undead are attracted too as it is quiet 

3 Train Line 8m high 12m wide two parallel rail lines where there are ruined carriages and blockages and floods but also many operating golem trains occupied by factions as mobile headqaurters

4 Kobold redbrick tunnels efficiently built and often directed by the Black Sphere. Traps and kobolds remain mostly 3x3m tunnels

5 Ancient dwarf highways from the great dawn age civilisations 9m high 12m wide, mostly full of vermin but goblinoids and dwarves still can be found in places

6 Goblinoid mazes of random carved tunnels varying wildly in size and safety. Traps, monsters and some goblinoids remain

7Ancient gnome highways from the time of the monster kings 4m high 4m wide

8 Burrows of great beasts in past ages or sometimes more recent like the great worms 

9 Giant Tunnels made in the dawn age when the titans were warring with the gods with portals to the faerie-like world of giant land. Many have elemental portals too and they were used for the preferences of giants who lived in them. Some nodes are spectacular lava pools or chasms or ice caves

10 Roots-filled passages a part of the world tree full of dark elves, goblins and fungus

11 Ancient wild natural caves of the deep Underland where the darkest most desperate creatures live

12 Strange volcanic glass and basalt tunnels made by beings of the outer void before the world was formed from darkness then water then land. Ancient horrors, shoggoths, crinoids and things best not named. Ancient evils often hide here until cults awake them

Trains

When a train stops...
Automated golem trains without crew stop according to habit or sub-ether communications from other golems and cognitive engines. Most of the train types are more dangerous

When you wave down a train...
Evil trains will often attack even just while passing
Balanced trains slow ponder if anyone looks worth helping or hindering or just drive away
Nuetral trains will stop and see if you want a ride if nobody looks violent but may help those they see as own kind
Good Trains might investigate and help anyone in trouble

Usually when a Lawful train comes to a stop at a platform:
1 Crew ready weapons at windows and wait
2 A party exit to secure the platform and declare under control
3 Scouts snoop around and beyond for signs of enemies
4 Officers and VIP might come out or an expedition will set off from here

Usually when a Chaotic train arrives: 
1 Crew take some shots at the platform

2 Crew pour out attacking at anything that moves
3 Loot the station and look for food
4 Start drinking, urinating, graffiti 
5 Volunteers sent on expedition

6 Bored leader will want to move on

Usually when a Neutral train arrives
1 Make a bell or horn sound to inform of arrival
2 Some passengers get off to stretch their legs while the crew take care of business
3 Will trade or drop off or take new passengers or repel attackers
4 Leave if dangerous or business done

Train Types
Each starts with an engine
Cargo ends with a guard train with cargo and post and guards
Passengers end with an observation car with a parlour inside

Handcars

d12 Train Engine Types
1 Kobold Express Train - built using salvaged dead golem engine scrap now automated by Kobold poltergeists. The engineer is a shaman
2 Goblinoid Gloop Train - overgrown with fungus and crawling with pets, the golem train seems alive and loves the ecology living on it 
3 Orc Pain Train - rusted armoured war train with artillery, operated by former black sphere orcs turned rebels against the masters. Train decorated in chains, blood and live enemy prisoners manacled up
4 Mutant Train - full of mutants who claim Chagrinspire to belong to only them who paid the most, many chaos worshipers and have mutated technology

7 Black Sphere Circle Line - black sphere millitary with elite riflemen, automatons and secret police
8 Dungeon Line - an intrusion from the dungeon dimension here for entertainment and to trap adventurers into the eternal dungeon dimension. Each car is a dungeon room. Once you get in you end up with the connected cars forming an eternal loop that increases in difficulty and teases you onwards to doooooooom!

10 Ghost Train - non-corporeal spirits in a spectral engine
