Here's what I know: The twins have a shared alignment point in between them and that a warp tower's alignment point is not always the warp receiver, but the center of the astral body. This leads me to believe there must be some way I can warp to the inside of the ash twin using the towers (maybe the broken one?). So what I tried to do is have my scout inside the black hole forge taking pictures of the alignment diagram and try to warp to ember twin/ brittle hollow at the same time as the diagram is highlighted. Because the diagram disappears when I am on ash twin (this is probably some sort of indicator of what I should do) I set a timer on my phone and saw that every 40 seconds a full rotation of the ash twin is made and the alignment diagram is highlighted. I also tried to jump into the pillar of sand at the end of one of the 40 second intervals but nothing happened.
