Yes, our current hyperspace drives shove us into witch space like the old ones, they're just better at it.
Fair enough. [up]
In that case, there's really no cause for complaint given that witchspace is some entirely abstract dimension, kinda like Star trek's "subspace corridors" - you've got no idea if they go directly from A to B or what might already be inside them so there doesn't need to be an obvious explanation for what you see as you're whizzing through them.
