A quick run down of what I remember off the top of my off the top off my head so be mindful I might be a bit off. It is also Varushkan focused sorry.
So last year with the treaty we signed with them we are get back a fair number of slaves and getting back I mean the Senate is buying them. They are also helping us against the Druj along their border and around Varushka and and helping defend the new territory of Ossium. The down side of that is they have build forts in Ossium and Karsk, Varsushkan territories. They are also pissed about the Liberty Pact but pleased with the Northern Trade Network linking them to Skarsind, Hercynia, Karov and Temeschwar.
Overall from my chats with the Ambassador last season things with them are as stable as we can get them at the moment. However expect to be saying “curse your sudden and yet inevitable betrayal” some time in the future.
