I just got in town from Thanksgiving with family, but we all caught a bad cold. I'm still a bit under the weather, and won't be active too much for the next few days at least.
Ah, a new fatherly mentor at her side throughout the galactic struggle sounds like a boss idea. In her profile, I made her NPC mentor a non-Force Sensitive, and he died in the escape from Hutt Space slavery. Aleyah is definitely missing that kind of role among her ship companions (only defined one npc, effectively a bodyguard). I think it would be cool if she met Gremont during her search for contact with the Rebellion, he'd definitely stand as a key acquaintance as someone to bring her into the fold.
While I've already started a mission thread for the Rebels with her, I wouldn't mind starting a thread that takes place before enlisting, then jumps to meeting each other again after the mission.
