"Many of them are the other worlds' versions of myself. Many others are other worlds' versions of my beloved. And their own friends from their own worlds, who are not copied here. There is a thing that happens to doors, sometimes, not when mages will it but at seeming random barring a few exceptions. I found such doors on a couple of occasions and went through them to a place where all worlds meet, and found one alt of my beloved, and later found another, and the second called his alt of me in to meet me. I was not well at the time. They healed me as best they could, and gave me my magic."
