you can specify it in the control panel. You have a few options like Aura, Karma, Alignment, Vibe or as i would prefer it Force (light side/dark side). and every type is gonna have the exact same function but a different looking meter/marking system the Force one for example could have a red/blue meter under the user's armatar like in KOTOR. think about it...
I think that allignment or force is kind of not fitting because if your allignment/force is bad/dark you also gain something from that. If your karma is low/bad u don't gain anything. Some more possibilities: mana, focus, blood, ink
Back to my previous post at the end of page 6, I think Piety fits right in there. You can have a positive piety, where your devotions are toward the contributions of society before your own needs, and negative piety, where it is the opposite.
Yes, I like nobility!! But think about ink. If your posts only get marked as spam, you won't be able to post any more (at least that's what I heard)! So it's like your ink ran out! You aren't able to write anymore!!!
Well yes, piety has religious associations with it. But the links suggest multiple, modern definitions of it. I see it more as "devotion to society/establishment/community" and stuff.
