What kind of rituals might take place if an emergency situation occured in which several men would need to serve as priests even though they'd had little to no training? Say, for example, a very small village that only has one priest for their shrine, and he is unexpectedly killed. Now they need some villagers to temporarily act as priests for a certain emergency situation. What kind of hasty, symbolic rituals might take place for this situation? Thanks!
More details: set between Heian and Edo periods. Very remote village in the mountains.
