I don't have an idea for a deity just yet, but I've thought of some sort of kingdom inspired by Orthodox Christian medieval countries like the Serbian kingdom and the Byzanthian empire, but with a twist - extinct mammals from the Cenozoic are the fauna. So, my idea for their champion is Mihailo - a massively talented archer who hones his arrows with the power of the Air Wonder. In his world, there are Fire, Earth, Wind and Water Wonders, and each have their own abilities and limitations. Wonders are a blessing from God, so they only occur rarely, and aren't something that can be passed down. So, in that sense, Mihailo's Wind Wonder is a blessing from his God. My champion rides a Palaeoloxodon to battle and is very hammy about making an entrance. :)
