Greetings,

Thank you for participating in the Diablo III: Darkness Falls, Heroes Rise Mark of Valor campaign. To reward you for your participation, an exclusive in-game sigil representing your hero has been awarded to the Battle.net account registered with your email address. Shortly after Diablo III is officially released, you'll automatically have access to this sigil whenever customizing a character banner.

Don't forget, each week a new hero will be featured, offering you the opportunity to unlock additional sigils. These items will only be available for a very limited time, so be sure to heed the calling of all Sanctuary's heroes!

Prepare yourself for battle,
The Diablo III Team
