Hera & Sabine
It can be difficult to forge something in a place where most don't consider it. Both in terms of convincing, and in terms of doing it well.
I'm going to start with, I'm rather glad you have it and not Maul.
Perhaps you should have thought about what the Empire might do with something, but you didn't have the experiences then that you have now. That gives you a different understanding and perspective than you would have then.
I can see something that was a Jedi object being of interest to the Empire though. Either for use to their own ends, or to destroy. You have enough clans in Mandalore as well, that they could be a push to the Rebellion, and perhaps more cynically, a distraction that could assist the Rebellion even if the goals were different.
