And the local Maitimo puts the kids to bed (early: they eye him suspiciously) and reads the notice from the Valar, sent out to a few dozen people who ought to be apprised of these things:
Urgent announcement: there are alternate dimensions. There are 'more than an octillion' of them. There is at least one, fairly capricious, means of travelling between them: an interdimensional bar called Milliways, which occasionally opens its door to people in random worlds. Someone from one such world found the bar, searched through its catalogue of all published works anywhere to find a well-governed dimension, and forked someone from here (with permission of an alternate universe version of the same person) to force the door of the bar here so we could help them.
There are other worlds like ours, except Melkor was paroled and is loose again causing havoc. In the world the petitioner was from, Valinor was destroyed with everyone on it; we are exploring how best to restore it. We are seeking assistance with planning and preparing for immigration from other worlds, developing a system for justice and rehabilitation to deal with people who committed serious war crimes but are safe to contain, and providing other forms of aid to other worlds. Please review and revise for publication.
He checks to make sure everyone was copied who should see this - yep -
