Okay so I was just wondering is there a item that you can change your alliance like I am a dark seeker can I change my alliance to a light seeker

Under 'realm', click 'marketplace' on the drop down, then head over to 'barter', then click on 'apples'. Scroll down for a bit, and you'll find 'Glacial ice', or something along those lines. It costs five apples. With it, you can change your faction.
