Players who have preordered Aion will be treated to a Pre-Select and a two-day Headstart period giving them the opportunity to explore, organize and progress through the game prior to the official launch. Pre-Select will take place on September 18, while Aion's Headstart will begin September 20.
It would be release in North America on September 22.
Keep a note of it!
Cheers,
Kin
