The other day I was checking on a sacked fort near my home fort as an adventurer and when I got down there it was basically yakety sax with occasional murders, as multiple dorfs and gobs were all running around from room to room fighting, totally ignoring me. After it calmed down I remembered seeing "The king retches" a couple times so I went and found him.
His name was Liceva Covarena, an elf name, it translates as Legendary Punchtruths, and he was a goblin.
Curious I checked up on him and found that he had settled in a nearby hillock named Townsink shortly before I encountered him in the chaos at Tomesplan, noting that Liceva was a member of The Crystal of Distinction, a dorf civ that had founded both sites.
I checked up on Townsink and learned that multiple necromancers had lived there, so I then checked up on the civ itself.
The first king of The Crystal of Distinction was a dorf necromancer, I walked in on the aftermath from The Balanced Immorality, a nearby goblin civ (well they're all nearby when there are 5 on a 17x17 map) which had recently sacked Tomesplan. There was apparently an uprising at just that moment and during this the crown passed to Liceva.
The first king, Bembul Copperbreach became a necromancer in 29, and apparently his wife had died in 3, killed by Tharith Zenithwar the Battles of Copper, the bronze colossus.
Townsink had been sacked back in 58 by another colossus, and then they attempted to reclaim it in 92 shortly before Liceva arrived.
I'll copy my more up-to-date save and see if I can figure out why he has an elf name after I eat, but basically that is why I love this game.
Besides all the other stuff you can do and play with, there is so much fascinating backstory tucked away inside it.
