First, I've just been tweaking some walls and adding some towers and shelters. Most probably I've made some really daft mistakes as this is my first steps at tweaking a game.

At Fort Sungard: A shelter over the furnace seemed like a good thing. Also on top of the mess hall, I chose to put another shelter.
There was a path along the battlements ending in a dead end. I put a tower there, facing west.

The pillar sky balcony now is built in and it's sheltered. No need to freeze if you don't have to.

North of the well, there was a ruined part of the fort. I erected the walls and added a way to the east tower via a set of stone stairs.

The oubliette now has a few minor changes.

Thinking of all the iron ore findings in the mountain, it seems odd that no one decided the fort was worth holding as a mine faction at least.
My bandit will attempt that and set up a mining company somewhere close. Maybe at Serpent's Bluff. I already begun fixing the tower and the bad walls of  that poor place of a redoubt. Now it looks promising. Just need to show them savages on their way.

I´ll be using Pocket Empire and Tundra Defense alongside Guild Starter to get my mining business going.
When I´ve earned a bit I´ll upgrade the fort to a better standard.

Until then.

May the seven be with you.
