In last book Ax becomes a part of a creature called The One, I have noticed that this creature bears a striking resemblance to Father (the seasponge in The Elemist). Is The one nothing but a space-faring version of Father or is there something more to him, it, they? I know that we were given extremely little information about The One, but what are your conjectures?
Personally, I think that The One is the entity that threw Cryak from his home galaxy.
