Summer Holy Days

Every culture in the known and understood universe has days of rest, of release. Even after establishing artificial drones to do all labor, or sticking to slavery throughout, there are still days of less work at regular intervals where they enjoy themselves, in one way or another.

Humans had 2 cycles out of 7, Esbadions 1 out of 10. The more religious cultures tend to have holy days, a small number every megacycle. These tend to be huge parties, or days of destruction.

The Riguians are having their first holy day in a thousand megacycles.

I'm sure it'll be fine.
