Visas Marr I recall "negative emotions" being the ones effecting the human brain the most. Visas' story contains everything of such nature; sorrow, desperation, pain... She was a slave of her own grief and heavily influenced by twisted believings. Still, thanks to (I believe) her dark side power not coming directly from hate, but from compassion to others, she kept a quite healthy awereness which helped her when the opportunity came to turn away from the path of despair. Miraluka is in general quite the omonous but still very interesting race; Visas is the prime example.
