So his main province is constantly trying to rebel as well. But when i tried Malekith, i went straight from having to knock out rebel Dark Elves to the south to literally 5 doom stack Chaos invasions from the north i never had a single turn spare to try and attack the Skaven in my starting province. He starts out with Skaven in all three of his cities, pushing Skaven corruption, but he has no way of even stopping it until he reaches City level 3, as that’s his first access to Public Order / Uncorrupted buildings. Her main province has a building chain that really cuts down the problems factionwide with corruption, but you need to get all the way to City level 5.
For me to stabilize a province i need probably 3 full time, fully upgraded, public order / chaos corruption generating buildings. Sort of like Vampire corruption, except her main province wants to decrease corruption. Morathi requires Chaos corruption, but has a hard time with it because she’s the only generator of it.
