Force Sensitive Archive

I just started glowing yesterday and im still waiting on the old man. I've read about people saving up their converted Xp so that when the right phase hits they can just unlock and fill up the branch. My question is how to you save it up? I mean my combat xp will max out at 900k, is there a NPC you go to in the village and trade it in for FS points or something?

thanks

Talkto paemos( in center) , choose what force branch you want the experience to convert to( combat, senses, reflexes, etcc..) , them convert. Rinse and repeat.
