At first glance I think it can do these things:
- Protection: put you in a “chaotic” bubble so negative forces can’t detect you and affect you
- Guidance: finding a way out of confusion, either caused to you or you cause it yourself
- Understanding of math and number and structure?
- Time and space traveling
This is a very basic interpretation based on the definition of the square and what Captain has said.
I’m sure it’s supposed to do more.
