Warning; I am not a religious person.
So there are various living gods and deities in the Mapleverse, and Clarabelle worships/serves one who... I am not sure I ever named. A god of fire, the sun, compassion, and knowledge. Basically, it's vaguely similar to Christianity, mostly the whole 'don't be a dick to people' part.
The closest analogue might be one of the Elder Scroll gods, like Arkay and Akatosh and those guys. Or maybe D&D, I've never played. Real, influencing people and magic, but also like. They generally hang back. They like having worshippers, but they don't need them as much as you might think.
