It does make sense. There have to be some base constants in common or else we would not be able to live in the same areas or eat the same food or, as you have mentioned, use the same magics.

I have never met with Sothis, no. I've met some of her children, but we are not on speaking terms. I have always wondered about whether godhood was a binary or a spectrum. The Church is hostile to other deities, so my information is limited.

I would very much appreciate you sharing your information about Tempering with me. Any information is welcome. It is a difficult problem and I have little help at home in Fodlan. I also am certain we need to return home: If we do not, there would have been evidence of people being Summoned in our home timelines. There are not, so we must be placed back.
