Within the next few sessions, one of my newly force sensitive PCs is very likely to be getting an NPC Jedi mentor. It makes sense and I would like for the NPC to stick with the group, but I'm worried about the NPC overshadowing the PCs. I've also never run an NPC as a party member, so I'm also worried about the pitfalls surrounding that.
I think my rough target is a bit like the relationship between Kanan and Ezra. Basically, someone that can train them during downtime but is also able to teach lessons in the moment (although that second bit does put a whole lot of pressure on me to come up with interesting teaching moments).
Does anyone have tips for how to run an NPC mentor like that?
