One lucky fun has won the ultimate "Game of Thrones" gift.

The author of the books, George R. R. Martin, gave away a throne to the fan that happened to be sitting in the right place at the right time at the HBO show's fan event in Brooklyn, N.Y., Thursday night.

The Barclays Center housed 7,000 "Game of Thrones" fans for a special advance screening of the HBO show's fourth season premiere episode. But before the screening, Martin called out a random audience seat number to give away an expensive replicated iron throne. Although not a one-of-a-kind product, it would cost someone $30,000 to purchase from the HBO website.

Luckily for Mike Ross, 37, from Hoboken, N.J., he doesn't have to dish out a single penny to get the most desired item of any "Game of Thrones" fan, according to Reuters.

Ross was one of 7,000 attendees that bought $15 tickets to the sold-out event. Many fans really got into the theme and went in costumes of their favorite characters.

Not only were these dressed-up attendees treated to a pre-screening of the new season premiere, but also to a Q&A with Martin and many of the show's actors, including John Bradley, Sibel Kekilli, Kristian Nairn and Maisie Williams.

HBO is set to premiere the fourth season of 'Game of Thrones' on April 6 at 9 p.m.
