Thank you CMDR.
I think I tried to decipher your meaning about this a few pages back and lost myself. This is much clearer. This means that this specific planet is a perfect place to draw a map of a certain astrological layout - every sunset or sunrise (of the ringed Y-dwarf) are identical.
This would imply that we should ignore the local bodies as their motion is probably quite complex compared to this 6.9 day cycle - unless they also fit neatly into the sunrise/sunset cycle of 1B? How can we find out or calculate this complex motion?
Someone reconstructed the system (or part of it) in an application recently (the interface looked very similar to Stellarium if I recall from the screenshot) - does someone know which post it was in or who did it?

There may be other bodies in the system that are somehow in sync with the 165.6 hours period. I haven't checked. The planet with the 90° tilted orbit, is a candidate.
For alignment of the ruin it self compared to other systems, it does not matter. Everything outside the system is in the same place, every 165.6 hours.
You can view the configuration as a clock. The Y-Dwarf is the short hand and the Moon is the long hand.
