After we make the fortress, expanding afterlife and making some guardians for it is a must. But let's make the update fortress only
So the project
My vision 1) It's a fortress of chaos gods, so no Urist's territory on it, he is just doing us a favor (By the way, don't forget to boost his farming for month, like we promised)
2) Weight is important, we should ask to use to use lighter materials and lighter construction when possible, explain that thing will fly
3) No high tech, please. (lasers, computers, internal combustion engines and the like) That's a metagame and breaks fantasy setting for me
4) Instead it should be armed with catapults, balisatas, mechanical rapid fire crossbows and so on
5) There are should be empty(potentially manarack empowered) central place to be filled with chaos energies , similar to the everburning tree, but suppressing order magic
6) Furnaces to smelt weapons is good, too. As any other workshops. Especially ones that use fire
7) Like 35% of the fortress should have fertile soil, for our plant based defenders\food production
It need to have a nest for dragons, to lay eggs here
9) Windmills to power various mechanics ( that's not high tech, that's dwarven)
10) Several huge propellers somewhere (either muscule powered or using mechanical power from the windmills)
11) Nests for various snakes and other animals
12) Ability to host... hmmm.. 500 civilians?
