This is, or at least will be, the Church of Ys, a place for I'm not entirely sure really. I like the idea of a big stain-glass window. I'm not particularly religious, but religion is a big part of the Ys story in that way that a lot of celtic nations became very devoutly Christian in a way I find interesting that speaks to a powerful magical kind of thinking in those regions. I think architecturally/design wise I'd take inspiration from St. David's and also the church I visited in Quimper. I did want somewhere a feature where people can randomly generate a single tarot card, and that could go here either in the confessional or, to be truly ridiculous, I could try stylize/stainglass the Waite-Smith Tarot...
