The big temple, as it should be, serves as a holy place, a school and a hospital.
Adventurers can come here for a variety of reasons. They can be called for help by the abbot of the temple, since strange events occur (for example, products disappear in the warehouse or the servants of the temple begin to get sick with a strange disease, or because something incomprehensible happened to one of the toilets).
Also, adventurers can come here on their own. heard that someone from this temple is associated with a secret society “long arm” and adventurers must find this person.
Also any other plot of your choice is admissible.
Combat scenes are recommended in a warehouse, school or garden.
