I see what you meant before. Luckily, there are two different ways to deal with it: One is making Consume Space an Extraordinary Ability (hey, if the umbral blot can make non-magical holes into the fabric of reality to teleport, I can make creatures that non-magically devour space-time); the other is simply going that Consume Space doesn't move the vizemut, it just removes the distance between them.
I'm eager to see what you have to offer in the later case.Next on the agenda's either some Fey or (finally) a new Deathless, depending on what I get around to finalizing first.
