So... I was running DF in with tech disabled, just to reminesce a bit. Mind you, spoilers ahead!
Urist McAdventurer, the first dwarf to strike out solo in history (worldgen rolled a single civ with extreme community spirit, dwarves do everything in minimum groups of 3) decided that it would be nice to take over a fortress after ten years* of wandering the world. He had accrued a wealth of knowledge that would give a slight advantage in all fields. He had become a legendary teacher, soldier and official from his various experiences. It was time to use all that for the community again (damn dwarven mind was on the verge of breaking, he demanded to be returned to a fortress by the gods!).
Then, this fortress was there. It was once a glorious capital. Even 1000 years after its fall to a united siege from 2 goblin and an elven siege (the goblins had no access to any forests, so they could ally with the elves) it was still considered the symbol of all dwarves. Restoring it would be the ultimate moment in Urist's life. The dwarf knew what the intention was when I arrived there, his thoughts suddenly changed to ecstatic. Just ecstatic. Nothing else. All the other various emotional axii were suddenly nullified. It felt like I'm checking the thoughts page of a dwarf in a player fort something like... 4 decades ago.
Of course, there were traps, but without tech, all it took was some quick reactions and Urist evaded them (I didn't train any trap making skill, weapon traps, pitfalls and cage traps are easily avoided by a well-trained adventurer, since there're no trap speed tech upgrades). Of course, there were carp. There was a waterfall going through the fort and the carp jump out of it while falling to attack Urist, but he just swatted them aside. It got a bit more dangerous with the skeletal carp though. It seems the river probably runs through an evil region somewhere, as every tenth carp is undead. Not that it makes too much of a difference to one such as Urist. No idea how the original inhabitants dealt with it though. Maybe it was corrupted after the fall by some necromancer or lich?
Ehm... back to topic. Sorry, I'm still bad at writing these.
As customary, there was a mine shaft that was dug just too deep. Of course, it was on purpose as a last-ditch effort to weaken the sieging forces, but it backfired. The ancient dwarves tried to seal it back, but failed to cover a single tile. Urist set to work and dropped a few stories worth of stone on the shaft for good measure. The demons already knew his name, so only few dared venture out, but it would've caused serious problems to any migrants later on.
Finally, it was time to go to the throne room, take the crown and declare the revival of Boatfall. This was to be the easiest part. Causing a cave-in and fighting on wet ground (rails still can't be constructed around waterfalls, it seems. I thought that was fixed already?). A single slip can really be fatal, as we know, especially next to a waterfall that goes straight into the abyss.
Then, on the throne sat a single dwarf, wearing the crown Knifemurder, among a countless number of other jewellery.
"I am Udim Vastborn the Harp of Stone. I have lived more than two millennia. I have killed..."
I stood there, pressing keys for hours. I later checked legends and found that the king was one of the first vampires, having offended some goddess of the night by drinking in the light of the full moon. During the siege, he personally created the mineshaft. It's likely he would've also exterminated the entire sieging force, but as a king he was royally forbidden from it. (Turns out he once read a book called 'The Monarch' and really liked it. It says something about how a single injury of the monarch may cause the downfall of the entire kingdom. Dwarves are still as influencable as ever...)
The thing is, while he was excavating, he breathed in some adamantine powder and fell into hell itself, where he was possessed by a demonic spirit, which let him fly back to the surface. He then proceeded to murder all survivors of the siege, both dwarven and not. Since then, he has murdered ever single non-fish being to set foot in Boatfall. He's also the reason why the place wasn't demon-infested yet, he was that much feared.
Here comes the strange part:
"I beg you, help me."
Udim's eyes glow red.
In a single moment of clarity, he wished to be freed. Despite being a vampire, he felt remorse for murdering all his brethren (I guess it's because it wasn't to feed himself).
Urist clashed with Udim fiercely. Still, Urist was no match for a demonically-powered vampire dwarf who had been killing for two thousand years. With all his might and acquired knowledge, he managed to flee, suffering heavy wounds.
I guess I'll have to get Urist to train a bit, probably turn him into a werecreature or something. Though he is getting old (I didn't notice, but he was quite old to start with already) so I might have to turn him into an undead, which might prevent him from ruling the capital, if he ever manages to reclaim it. Any ideas? I could try enabling tech mid-game, getting Urist to do as much research on weaponry and longevity as possible then disable it. I don't want my enemies suddenly appearing with guns and killing me. I'd prefer skills to have a greater effect than that.
Also, is it a bug that the king wasn't mentioned as an inhabitant of the ruined Boatfall? The legends say "no defenders survived". He only has former memberships in civs and legends only list his kills, but not as a part of the siege. Actually, everyone who went to Boatfall previously is only mentioned to have "died while exploring the ruins of Boatfall."
