CUSTOM campaign frames + Stories

I’d love to start a discussion on custom campaign frames, currently I have two separate ideas. One is about 3/4 of the way developed the other one is simply a sentence.

One thing I’ve noticed with the heart of daggers community; you guys give amazing advice, so I’m wondering, what do you guys think is the most essential parts to a successful campaign frame that I can implement?

My current worldbuilding project and its key details for refrence:

Myrn is an ancient, melancholy fantasy world shaped less by grand battles between good and evil and more by people, places, promises, and the weight of history. Magic exists, gods are real enough to leave questions behind, and legends grow from ordinary people caught in extraordinary circumstances. Myrn is intimate and local: who you know, where you come from, and what you choose to value matter.
