Then the royalty apparently got even more decadent and screwed up, leaving Alissa in charge (with no one going against the crazy bitch) which made them an easy target for Kasyrra.
I don't think this is exactly what happened. IIRC, Ryn's grandmother was the one that made the deal with Lumia, which, again, fair, because it was either that or getting ganked by wraith beasts. Ryn's mum I think died in childbirth? Ryn's dad was entirely unfit for ruling - he reminds me a lot of GoT's Robert Baratheon, who was an incompetent buffoon at ruling who basically did no ruling because he found it boring (actually, Bob ALSO died via boar while hunting and no blame could be determined, so maybe he actually WAS the inspiration for Ryn's dad?). As I understand it, he didn't do much active damage to the kingdom (Baratheon literally ran the treasury dry with parties), but honestly that might have been because he didn't have enough time to, thanks to the boar. There's not really much increase in decadence until the Alissa rule.
Fortunately that entire problem is solved now, because there aren't any nobles left to run the place into the ground, except for Ryn, who's actually ruling, and Daliza, who actually seems competent at her job.
knocks on wood
IIRC correctly, Ryn's grandmother is also the one responsible for moving mining away from, well, mines and establishing the prospecting operation on the Glacial Abyss. That backfired spectacularly, but it's actually a good example of good ruling, because from the tidbits you get from... the jotun encounter, I think, things were working quite well until the elves decided to expand the thing beyond sustainability and fucked things up for the natives. I don't think we're told WHEN that shift happened, so I couldn't tell you who was in charge at the time.
Winter City does sorta have a chance at a clean start. We just have to ensure Alissa doesn't get to come back and fuck things up again.
On the Winter City front, I'm way more worried about the Alliance than I am about Alissa. I expect we'll have to storm the Lumian keep I keep hearing about to sort it out, and half-expect being given a choice of expanding the whole prospecting operation (fucking over the natives) and beating the ever-loving shit out of ever valkyrie in situ.
*for refusing the convert to Lumianism.
They went on a sex strike to try and snap Athel out of being a chode about the druidic schism, but that's not why they were locked up.
(Just a point of fact, not saying Athel was not in fact a giant chode about it)
Huh, maybe it's because I'm not a native speaker, but this was DEFINITELY not how I understood the order of events as they were explained during the catacombs mission.
What I understood from that was: Lumian conversion -> Harem says this is a bad idea -> Athel keeps on keeping -> sex strike ensues -> Athel locks them all up for it instead of telling them to fuck off and join the druids if they love them so much.
Thanks for the correction.
