A real wound will pay any price for relief, including a price that buys no relief at all.
A wound that has been seen and named raises the need for certainty to an emergency, and an emergency collapses the search radius down to whatever power stands nearest with an army. The state does the choosing before judgement gets a vote, so a king becomes the vehicle for a cure no treaty has ever contained.
The God speaking the diagnosis stood inside that radius the whole time and was never asked, which is what an emergency state does to a person's list of options. Every alliance bought in that condition arrives with a master attached, the tribute begins, and the wound that started all of it is exactly where it was.
