Alright, so I see this in a remote oasis city in the desert, where our characters would be free to train and assist the population when their are not praying to the Goddess of Light and training their body, mind, hearts and souls. Say they are just starting, so their training will be about strength of body, scholarly pursuits and compassion, adding prayers and divine boons as we go along, from healing touch to purification of matter and exorcism.

Since this is a slice of life, you are all free to add things if you want, as long as they don't contradict what is already said.
