If you fall back down here after completing puzzle you will be unable to leave and have to creat a new realm.
Actually that’s not true. I got stuck in the same room but you can get out on the right side right below the bridge. Try it. Took me about 5 min to figure it out.
I tried jumping up before posting no luck looks like you should be able to but not working over here.
Sorry to hear. Worked for me. There should be an unstuck feature or a town portal scroll or something similar for a situation like this.
