Got bored, so I abandoned one of my seasonal saves so that I could go looking through the history of my Mountainhome. (I went for a high number of civilizations in world gen, and as a result, few civilizations are very big. I am sad to find that this does not mean any pre-built ruins.)
After digging around some, I finally tracked down the history of Iden Silverytax, First King of The Cunning Roughness.
Tosid Blamemurders, that bunny-devouring cougar of ill-repute, died peacefully of old age two years later.
So, apparently, a lot of my foredwarves died of starvation while issuing royal mandates. Thankfully, they seem to figure out how to grow crops by around the year 51, though they don't seem to know how to raise an army.
Those two dwarves who got piked were my general and king. And you'd think that, having pillaged my capital, The Dark Plagues would have taken over the kingdom. Only, it seems that Logem Wallbowels must have pulled some kind of fast one, cuz now she's the queen of my dwarf-nation, and is getting attacked by the goblin general who won her the kingdom in the first place. o.O
Actually, it gets a bit stranger than that, because according to Logrem's bio, she gets abducted in the second assault and that's when she gets turned into a Monster Bride of Twilight.
So....that's what I'm doing.
