here are some ideas/wants i have!! going down in how hard it would be for the devs to add

a special quest with the shepp where you go on a little adventure and they have dialogue teaching you about majiri and kilima culture (and maybe their paths/interests too). ideally this would work similarly to the temple quests where you get to unlock a new place. maybe add a building that you can't get into until you complete the ceremony and fully become part of the kilima community? visit another town? idk man just something nice and rewarding

a separate shepp relationship level alongside the friendship and romance ones. it would just be with your shepp (obviously), and increasing it would involve conversing with them using the shepp option (dialogue would include teaching you about majiri & kilima culture, their path, their life experiences and beliefs, etc) and Maybe leveling up in their path if that's possible with them (ex: reth with cooking). for certain levels you get gifts that are unique to the character and their path. this would incentivize players to really think about who they want their shepp to be and not just choose their fav blorbo!

you talk to them after the ceremony and they gift you a placeable guidebook about majiri and kilima culture that they wrote themselves (so unique to each character's personality) and that you can actually read (like the books that you can read around the map)

a weekly challenge related to their path/interest. i'm not sure how they'd implement this for characters like caleri or chayne since their paths aren't part of the gameplay like cooking for ex but,, it'd be cool lol maybe for those characters they could add like a,,, talk to that character x amount of times challenge?

add casual dialogue centered around them being your shepp like "hey remind me to teach you about this thing" or "have you heard about this thing that we do" or "hey you've learned a lot blahblahblah" and maybe dialogue from other characters about them being your shepp (similar to the romance ones). they could give their opinions on that character or even ask you how it's going
