Wee, what a great idea!

I love this age.
My solutions:
Preparation:
- Start with sphere 1 in the active position (quabs cleared, current off) and link into it by any way.
- Swim to the maintenance area and touch the cloth there.
- Swim back to the island and rotate by linking to the Cathedral.
- Use the bookmark in Relto to link to the maintenance area of sphere 2.
- Have a buddy rotate the spheres twice.
- Touch the cloth where you are (maintenance are of sphere 2).
- Rotate twice, either by linking Relto - Ahny Sphere 1 - Cathedral - Ahny Sphere 2 - Cathedral, or by having your buddy do it.
- Use the bookmark in Relto to link to the maintenance area of sphere 4.
- Pull the door lever to bring sphere 4 into the active position.
- Use the bookmark in Relto to link to the maintenance area of sphere 1.
- Swim to the island and touch the cloth there.
Now the described sequence can take place:
Your avatar stands on sphere 1 (watery). There is no one in the maintenance rooms and no one in Ahnonay Cathedral. You rotate sphere 1
by linking to the Cathedral or pulling the lever in the maintenance area. You come back to sphere 2
by linking from the Cathedral or maintenance area to Relto and using the bookmark there and rotate again
by linking to the Cathedral. You come back to sphere 3
using the bookmark and rotate again.
You come back to sphere 4 near Kadish statue
using the bookmark !!!
Preparation:
- Start with sphere 1 in the active position (quabs cleared, current off) and link into it by any way.
- Swim to the maintenance area while having a buddy turn the spheres once.
- Touch the cloth in the maintenance area.
- Pull the door lever to rotate back.
- Send a buddy to the maintenance area of sphere 4 using the bookmark on Relto.
- Link to sphere 1 using the linking panel.
- Touch the cloth on the island.
- Have the buddy pull the door lever.
- Both leave the age using their Relto books.
Now the described sequence can take place.
And here’s how to puzzle Kadish (not the only solution and maybe not even the simplest):
- Link to a fresh Ahnonay together with a buddy.
- Clear the quabs.
- Touch the cloth on the island.
- Let your buddy go for a swim so that they’re off the radar.
- Link to the Cathedral to turn to sphere 2.
- Link to sphere 2.
- Touch the cloth at the side of the tower.
- Have your buddy link to the Cathedral to turn to sphere 3.
- Link to Relto and back to Ahnonay by bookmark. You arrive on the tower island in sphere 3.
- Touch the cloth on the tower island.
- Link to Relto and back to Ahnonay by image. You arrive on the main island in sphere 3.
- Link to the Cathedral to turn to sphere 1.
- Have your buddy you meet there link to Ahnonay (sphere 1).
- Link to Relto and back to Ahnonay by bookmark. You arrive inside the tower in sphere 1.
- Turn off the current and open the tower door.
- Swim to the maintenance area.
- As soon as you’re off the radar, your buddy can link to the Cathedral to turn to sphere 2. Their assistance is not needed anymore after that.
- Touch the cloth in the maintenance area.
- Swim back to the island and link to the Cathedral to turn to sphere 3.
- Relto out and link back by bookmark. You arrive in the maintenance area of sphere 2.
- Touch the cloth there.
- Relto out and link back by image. You arrive on the main island in sphere 3.
- Link to the Cathedral to turn to sphere 1.
- Relto out and link back by bookmark. You arrive in the maintenance area of sphere 4.

- Link to the Cathedral to turn to sphere 1.
- Link to Ahnonay, run around the island, and link to the Cathedral to turn to sphere 2.
- Relto out.
Now the sequence shown in the video can take place.
These are all untested. I could test them using my second account, but doing it with a real buddy is more fun…
I have tried to come up with my own puzzle in return, but unfortunately I found that the sequence I had in mind doesn’t work due to what I consider a bug in the age’s wiring.
Edit: A modified version of puzzling Kadish that also gets you the hidden Relto page (clock or thunderstorm, don’t remember which) – modifications in bold:
