There was no way Eston could have gotten on you. (Well there is/was, but that would have needed some other major changes on current setup).
Darka made pretty clear that Anost stay at property of Silnaria to Eston and to Silnaria as well.
Eston didnt get away from it... their ruler had to take a rest cause of those plans.
I have no clue if Rielston/ML were planning to jump on you, but as long as Darka were able, it would have kept western border secured, just to make sure Anost stays under Silnarian banner.
But lets see what happens... and if there will be new King, where he will stand... will Silnaria go back on line as Central big boys order, or will it still try to maintain its independence.
