Glad to be in that company, lol!
The thought I had is that it's to spare others, but I've been thinking a lot about what the victory (and the failure) should actually look like. And I'm also toying with how I might adapt some ideas that aren't so heroic. For example, you have your Allies, but they may not share that goal, so depending on how things shake out there could very well be some trade off that gets you closer to your goal or more innately powerful by abandoning your Allies. But it's all for the sake of saving others from your fate, right?
Lots to consider with the design space, and I'm getting more comfortable with the system so I'm hoping I can pull off some interesting things!
