While Tatters and Stevje are focusing more on the fae side of Britain, I'm going to be focusing more on the Church side of things. Here are some things I am thinking:

- I am going to borrow the Dark Age thing of referring to the messiah figure as Bloodless Xristos. This is because I am not at all skilled at or entirely comfortable with using actual biblical references. This also sets me in a comfortable space where I can confidently make stuff up without worrying if I've gotten 5th century religious doctrine wrong. 
- Further, this is [i]fifth century[/i] religious doctrine. It's extremely focused on mysticism, sorcery, pilgrimages, and esoterica. There is [i]no [/i]line between religion, science, magic and medicine, and there has not been the hammering out of doctrine in church councils. Xristia is extremely freeform and heresy hasn't been invented yet. Wizards will seek out the church because they reason it will make their spells better. A doctor might go on a pilgrimage to learn how to cast a spell to relieve pain.
- Accordingly, Felii knows how to do exorcisms, break curses, and do cast some spells of her own. She personally has no idea what the origin of her magic is, it's a freeform mix between wizardry, prayer, and faerie bargaining based on the situation. 
- Felii is very unusual for her study of magic while serving as a Knight. It's a family tradition dating back to her ancestor, the Paladin of the Threshold, who defended the Emperor against arcane threats. Her family is kind of Belmont-esque in that they've accumulated a [i]very [/i]significant store of mystical knowledge over the generations. But, being based in Constantinople, they haven't had much opportunity to actually fight monsters recently, meaning her sisters have mostly slipped towards being more standard knights. Felii took a particular interest in magic as a seventh daughter, which gave her a natural knack for the Art.
- Juliet the Apostate is the current empress. She is attempting to syncretize the faith with the Egyptian pantheon. The Egyptian view of the afterlife is a massive cultural influence on the Church, much more so than the Greek.
