I got it, thank you! I did do Cassandra's side quest, but before I put in the code, I don't think I was able to progress even after pressing the 2 switches. It was only after I inputted the code that a walk path appeared to progress.
Can anyone help me? I'm stuck in the garden of illusions, where you have to put the code in for the blue crystal. I can't for the life of me remember anything about a 4 digit code for a blue crystal
