Or untill SA decide the marching the length of the continent... Every attack is just not worth the effort...
Nor worth the effort? I'm sure there are plenty of Aurvandilian coastal region greedy morekian knights could go offload onto and pillage a bit before returning home. Perhaps with a few battles here and there. Gold and opportunities for honour, prestige, and to prove oneself. Why wouldn't they continue attacking?
In any cases, the current wars are the result of long-dating tensions finally breaking out into full-out conflicts. Things are evolving quickly, and I must say I find it all pretty exciting.
