Really? Isn't Astrum one of the densest realms? It's one of the most populous, at least, though it's quite large.
It's not especially dense...though it may be more dense than the average on the continent, I forget.
Also, that's brutal. XD Is that to target Eidulb itself, or only to transit towards eastern targets?
That was to move to Eidulb, and then figure out what to do from there, IIRC.
But this was all just in local testing; that level of monolithic movement was one of the things I wanted to do away with, and I believe I've been successful.
