Can you suggest a good feat?
What about 'Own Species' as area of influence?
I'll look into Feats. Any particular direction you want to go with this character?
You can have Pak'ma'ra Civility as an influence, which covers all aspects of pak'ma'ra society, politics and military. Pak'ma'ra "government" is all mushed together into informal councils and deliberations.
Edit: Some Feat ideas:
Some B5 specific feats that might be useful -
Contact - gain a contact, gives expanded use of Influence
Hobby - make a skill a class skill.
Spacecraft or Surface Vehicle Proficiency - ability to use spacecraft or heavy ground vehicles without penalty
Latent Telepath - some minor teep abilities
Independently Wealthy - extra money!
Data Access (you meet requirements) - faster computer searches.
Alien Anatomy is worth considering as a doctor character, but you need 6 ranks in Medical.
Otherwise, standard d20 feats like the +2 to save ones, Endurance, Toughness, Skill Focus, Combat Expertise tree, Imp. Initiative etc.
