Apparently the reason why the URSR is so dug in and loath to do strategic withdrawals is because they're protecting a dormant Votann. At the heart of their territory is an artificial planet housing an inactive ancestor core that they believe is one of the first of its kind, if not the very first. Seemingly they have told no one about this. And since the URSR don't know how to boot the core up, they can't verify their suspicions. So for the past however many thousands of years they have essentially went through a list of every known activation rite and cipher with nothing to show for it.
