I've made a lot of promises. Am I expected to keep *all* of them?

I formed a tribe! Awesome! The saga of my glorious clan and its many HeroQuests will surely ring out for many years. When negotiating to form this tribe, I made many promises. Some of them, I know, were kept automatically, such as allowing a neighboring clan to build a tavern on my Tula. Others... I'm not so sure about. Most notably the promises I've made to honor various gods with annual sacrifices.

Do I need to manually perform these various rites annually, or is this handled automatically behind the scenes like other promises? If the former, is shrine/temple maintenance sufficient?
