@ Swampman

Yes, I think there has to be some sort of "grace" period.

Presumably something changes in the cosmos when a potential will is born that makes the Seneschal take note.

Perhaps at any one time there can only be one Arisen in the world, or one compatible will to accept the mantle / journey?

Afterall, we know of at least 2 other countries in addition to Gransys (Julien / Mercedes's homes) and so each of these countries could have someone of the correct age. However, neither of these countires appears to be suffering a Dragon attack at the same time as Gransys as they are 'lending' (I use the term loosely) their aid in some form. Therefore this leads me to assume that there is only ever 'one' Dragon pursuing 'one' Arisen / will-to-temper.
