Decided to try starting a game of Elder Kings as the colovian estates, seeing as they somehow always manage to take a huge chunk of Cyrodiil in any of my other starts. Took over all of Tamriel way more easily than usual due to their OP-as-fuck government (more on that later). Switched to observe. 300 years later, Tiber Septim killed+replaced the emperor and a revolt made about half of the continent independent. 400 years later, everything was back together (including vvardenfell, bafflingly; unless something's changed, vvardenfell is nigh-impossible to invade because Vivec gods up million-strong doomstacks if you try, though I guess since the AI did it it's possible now). I decided to mess around a bit and interfere, so I took control of a duke, made him a worshiper of Mehrunes Dagon using the scholarship focus (if you study Oblivion with your observatory, you get the opportunity to hire a daedric scholar, who can make you cult of whatever daedra you want), then added enough offmap currency ("ardor") to ask Dagon to start the Oblivion crisis. After that, I switched back to observe.
They took care of it just fine. At the end of the crisis, the duke ended up controlling half of Solstheim, then that got swallowed up too. Tamriel endured.
Now, the reason for all this is that the Colovian Estates has a government type called "confederacy". They're essentially feudal, except the top-level title has these changes (all vassals are feudal):
- Liege has -2 to demesne limit
- Feudal Elective is the only available inheritance
+ Liege has +10 to vassal limit
+ Vassals cannot have their armies levied, instead being called to war like tribal vassals.
That doesn't sound like a +, but holy shit is it good. The minor disadvantage of not being able to control your vassal levies is outweighed greatly by the massive advantage you get from having all of your vassal's liege levies available and the total lack of opinion malus from calling them to war (in fact, you get angry at them if they refuse). This also allows you to set the noble obligations to tax-shifted as far as you want without any disadvantage whatsoever.
Feudal Elective is a bit of a boon, too. Elective is, of course, pretty amazing if everyone loves you, since they all vote for who you want anyway, but in observe elective meant that the realm was insanely stable, with only Tiber Septim (an event usurper) causing any trouble. The only other revolt I saw was approximately the size of two dukes, and was quashed within the year.
Anyway, Septim's dynasty died off after one generation and the character I used to create the emperor's dynasty ended up becoming minor barons and a single duke. This was all well and good; I mostly just wanted to see 1. how the "call to arms" mechanic affected wars (see above) and 2. I wanted to get a nice observe game with the empire of tamriel to see how stuff could go wrong. All of the empires after were descended from my first guy (a dragonborn emperor, since that or the Amulet of Kings are required to create the Empire of Tamriel title, and the Amulet of Kings suuuuucks, it's got an MTTH of 50 years or so and I'm actually not sure it even works in this update, so I literally just cheated the event in since after three or four attempts at getting it with immortal controllers of sancre tor in various saves I never got a single event from the council job that ought to give you them, even ones with MTTHs of something like two years), so they all had dragonblood, which was interesting.
I can't overstate the stability, it was almost disappointing. Last time I'd run an observe game to the year 4200 as I ended on this time, Valenwood had somehow become the Bosmeri Dominion and most of Tamriel had become Green Pact religion, with only pockets of ALMSIVI in Morrowind and Eight Divines in High Rock. This time, the Eight Divines faith got to 100 moral authority (it usually starts around 50) and stayed there. My first emperor would have become Talos, the Ninth Divine, but Tiber Septim event murdered him so it didn't happen. Maybe I should have killed him before starting the observe, I don't know, having an immortal emperor is a bit boring for stability reasons. Hindsight is 20/20 and all.
I'm baffled at the Oblivion crisis failing to cause any issues. Seriously, it spawns 45000 attritionless (!!) troops on your capital, then opens more Oblivion gates all over Tamriel with even more event-spawned troops to mess up the place, all of which have separate warscore, but it didn't even make a dent. I guess the emperor at the time had over 30,000 in retinues and the vassals were no slouches either, so it's not particularly surprising, but god damn.
