Right, sorry for the long silence. Shortish update, more to follow forthwith. And remember: This fort is built on YOUR SUGGESTIONS. So the more you say, the less ways to make it Fun I'll have to think up myself! :-P
Anyway.
After the stupid idiot demon Master trashes the entire hospital, you decide you've had enough, and it's time to seal him up. You attempt to wall him in after he walks back outside.
Unfortunately, the jerk realizes what you're trying to do, and objects strenuously.
Caught off guard by his sudden burst of coherence, you try to come up with another plan.
You come up with a brilliant plan: Dig a hole under him, THEN wall him in. Perhaps, if he's in a pit, he won't notice the walls going up.
It backfires horrendously. As soon as the pit is dug, he realizes the plan and goes on an enraged vandalism rampage, completely pulverizing two hovels' worth of furniture before marching right on into the apartment complex you've seized for your bedrooms. Fortunately, you have so much lovely stolen furniture in there for him to break that you're able to wall him in long before he's done smashing it all to splinters.
You seal him in, but sadly he takes a half dozen fully stocked barrels of muskrat lung and other such delicacies.
You set to work rebuilding the hospital, building new beds and stealing the chests from all of the shops. You also steal the coins inside.
Lastly, you turn the keep into a somewhat more defensible location by sealing off the broken doors, disconnecting the top of the keep from the nearby hill, and connecting it via underground passageway to the inn.
With all these distractions, though, you've barely done any planting. Good thing the humans have quite a lot of meat on hand. Those firefly brains won't last forever, and it's nice to know that you'll have plenty of chopped horse udder to fall back on.
You begin work planning a system of tunnels to connect everything underground. Hopefully you can do so without running into any aquifer problems.
