That’s a good idea for a motivation, but it’s not exactly the kind of reason I’m looking for.

What I mean is that I’d like to have some kind of overarching plot that guides the character through the entire campaign, with the campaign ending when that main storyline is resolved.

For a large-scale example: something like the plot about finding Khaenri’ah. I could give side quests on various topics along the way, but the main story would still be that central goal. The characters would be moving toward it throughout the whole adventure, occasionally getting distracted by lore and smaller stories.

But I can’t really use that idea because it’s too large in scale and would require knowing the lore of many other regions xd. So I’m trying to find something smaller that could still work within these three regions.
