How do I change factions?

The first time I was at the Temple of Ages, I gave 1K to Balthazar guy, just to see what would happen. I later found out I should have talked to Grenth, since I'm a N/M. Does anyone know how to change factions? Also, is there a way to change my current faction points to Grenth faction points?

The avatars at the Temple of Ages have nothing to do with Faction. Talking to them will gain you access to more difficult areas. Fissure of Woe and the Underworld.

Faction is a point reward that you gain by competing ing PvP. It can be redeemed to unlock items for PvP only characters that you create.

There are no factions the way you're thinking. The closest there is that comes to it are American, European, and Asian servers.

And like Autie I mentioned. Faction (in this game) is a PvP reward that you collect and spend to unlock items, runes, and skills for PvP only characters.

faction is something you get for fighting and spilling blood in PvP, thats why its ascosiated with the god Balthazar. In the future they may add faction for the other gods, so for Dwayana you may get faction by helping people or by healing and resurecting others.
