So, as an example, for Palilas starting skills;

Brawler: 2 (+10)
Con Artist: 2 (+10)
Cat Burgular: 2 (+10)
Hacker: 1 (+5)
Medic: 1 (+5)

Reasons being--- Palila has a background of playing rough in the streets (brawling, but not super high) as well as being quite chatty and convincing authorities not to put her in trouble (con artist, again, not super high). Acrobatics is a skill she has demonstrated in-game and in her history; knowing how to backflip, balance, surf, skate, etc. (So therefore, a few points in cat burgular).
She has struggled with the technology of this region, but has managed to do some basic things while under pressure (a single point in hacker) and she has - in her profile- an immunity to and experience with poison, due to an experience with a tentacruel when she was young (a single point in medic).
