Not surprising, the Seal magic that happens is something I don't fully understand either. Sometimes I think it has a point, but other times I wonder if it's random. Oh yeah, we get wishes around Christmas. A singing bauble, usually, you make a wish and it happens.
Wishes can be literally anything. Well, only ones that affect you. You can't wish anyone hurt or dead, and you can't tell it to bring anyone from home. But you can have unlimited money, or powers, or magic abilities, or to have anything from home like a house or special weapon, or anything else that you used to own that isn't here.
