There are still some shadowy areas. For example, in my experience moving a kin leader (twice with alts/scouts on other servers), the kin wasn’t disbanded on the departure server. This, in a way, is reassuring as we’ll still be able to communicate through the kin channel in this case.
Otherwise, the senior officers plan to leave a lower alt behind on Meneldor anyway, as long as necessary to make sure everyone makes it safely to our new home.
