Ellis credited as 'mastermind and co-writer' with some other dude as co-writer. And this solidified my thoughts that usually, unless both writers are known commodities, this type of arrangement is shitty.

Ellis obviously wrote this around the same time he was working on Authority and Planetary, since the central tenet is Nate Grey as 'mutant shaman' and it deals with multiversity heavily. It comes out pretty much totally half-baked, lame. The first arc is almost C grade, a mutant secret society up to no good in the multiverse (which, for some reason, they needed space suits to explore). But the second arc - featuring Maddy Pryor revealed to be Queen Maddy Pryor of Earth 998, revealed to be Jean Grey exiled from some other Earth - was just terrible.

Overall the worst Ellis-associated project I've read by a mile, and confirms the belief that ideas from the Big Idea guys are only good if the Big Idea guys themselves are writing them. Anything 'bbased on ideas by ____' (DC guilty of doing this with Morrison a lot, especially in the post-52 ere) is going to be subpar.
