R15, Kioet can't get to a VSD; he got to the base via a special transport. So he has to take it back to get there quickly. Normal hyperspace travel takes about a day, give or take. (Too lazy to calculate it, but the base is out there)
Scar: I was following the logic of Irvine pulling Kioet into the realm via a 'connection' with him. But I still don't see how Irvine could know how to teleport instantly across the galaxy; are there signposts or something? "This way to Tatooine"? How is he hopping and still keeping his new physical body, since he discovered hopping with his 'spirit form'?
By the way, Sleepers don't have a 'standard set' of powers. And Cracken was a special case.
