"Game of Thrones" and the American Red Cross are inviting you to prove your dedication to the throne by donating blood at South by Southwest this year.

From March 7 through March 9, the HBO hit will host a blood drive and immersive experience at Fair Market, allowing guests to "walk in the steps of those who bled" from the show after they donate. Giant Spoon, the agency that put on last year's SXSWestworld based on HBO's "Westworld," are heading the "Game of Thrones" experience, Adweek reports.

Blood donation appointments are highly encouraged. You can still walk through the immersive experience without donating by registering.

Outside of SXSW, "Game of Thrones" and the Red Cross are hosting "#ForTheThrone" blood drives across the country. Give blood by March 17 and you’ll have the chance to win one of five trips to the season 8 world premiere of the show's final season. If your donation is between March 7-12, you'll score a T-shirt and sticker.

What would you do#FortheThrone? Show your@GameofThrones pride and sign up to donate blood with us. Come to give by 3/17 and you’ll automatically be entered to win a trip to the season 8 world premiere. Make your appt now:https://t.co/Utl46ltDjHpic.twitter.com/DZTio1zLjb
