Erik is a good guy. He tells you more about the Alignment Points.
"Don't let my scar fool you, I'm probably one of the nicest people you'll ever meet! See my gold name? It means I have 100 ap, or alignment points. I haven't hurt anyone in a while, and I've done good things to raise my AP. It also goes up over time. With my gold ap it means I can't be hurt by other player swords!"
