Gods play an integral role in Homeric society. They are very active in the lives of humans, both in wartime and peacetime. People depend on the gods to help them fight wars, protect their loved ones, and just improve their everyday lives.

This can cause a very volatile situation where the gods are likely to let you know they have not been honored enough for their liking.

Chryses prays over and over again to the god Apollo asking for help with the return of his daughter. Chryses reminds Apollo of all the ways he has paid tribute to him over the years. Chryses built a temple to Apollo where he is the priest. He...
