How would the elves respond to Tin sending over a few more hordes to the islands? Would they see elevated military presence and then immediately go to war?
[/quote]Nobody would "just" go into war for that.
They would raise their alert level and perhaps even ask for reinforcements.
Given the talks with Avalia and PRK I think they might even see that as a good excuse for making the preparations for war, though.
Zanshir currently has about a hundred thousand soldiers, unusually high for a colony/province but given the presence of vaguely hostile elements it was a well-founded precaution.
Still, if Yllendthyr ever wishes to fight Tin they need far more than that.
