It was called Terra. It was a realm outside of time, a little like this one. People usually seemed to arrive there without reason or pattern, and depart the same way. I still don't know why I was there - or why I am now here. I could write home from Terra, though. Some trick with enchanted parchment. It doesn't work here.
I think I'm fifteen now. I was fourteen when I was sent to Terra, and I was there for some time.
