Beginning at 9 a.m. EDT on Friday, HBO2 will air each "Game of Thrones" season in its entirety.

If the "Game of Thrones" marathon on HBO2 is not enough to satisfy your appetite, HBO has released an interactive episode guide that explores the locations, people and houses that make up Westeros. The "Game of Thrones" viewer's guide includes videos from the series creators, actors and "Song of Ice and Fire" author George R.R. Martin as well as galleries, quotes and other features. The interactive "GoT" episode guide also includes a handy Appendix that provides a good recap of the history of Westeros as well as other important elements of the series, including Robert's Rebellion and the settlement of Westeros by the First Men.
