Diablo 4 Side Quests

With Diablo four, we did put a particular emphasis on trying to tell the best story that we have ever told see if we can do better than we've done before. But, but I also want to acknowledge that the story is big, right, and there's so much additional content beyond the golden past story. How do you keep the main story connected across all of the side quests? And with the option to sort of proceed almost non linearly how do you keep everything feeling coherent as you're moving through the game.
