Well, I used the plate glitch to get through the locked iron door and then just had to go outside!
By Sithis.......I have seen the void!
I then got on the roof of the circular ruin, and ' Wuld' sprinted to the nearby mountainside. Odd that these mountain appear right next to the sanctuary!
Finally, with much running and lateral movement I made my way to the very top of the highest peak to survey Cyberspace in all its weird glory. Far below me , the sanctuary, and above a stormy and slightly purple sky.
That's a save to keep for a good while!
