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?
I believe all of the promises are handled behind the scenes. I have never had a clan leave because I didn't sacrifice to a god or have an altar to one.
Rather than requiring the promises to be fulfilled by the player, making too many promises is punished at two points.
The first point is the actual tribal moot.If you have made too many promises, particularly any conflicting promises, you will have trouble successfully forming a tribe. You already got past that part though.
The second point is promise related events. For example, there is an event where (iirc) your women destroy the tavern built on your tula, because they are tired of the men getting drunk. Then you have to deal with it by repaying the tribe and letting them rebuild, repaying but not letting them rebuild, doing nothing and risking them leaving, etc.
