A new interactive Game of Thrones guide from HBO has arrived to clear up any confusion you may have about Westeros, Essos, their inhabitants, their houses and more.

HBO launched the guide just days before the show's April 6 season four premiere, and for those of you who aren't completely caught up, the guide has nifty spoiler filters.

Point being: Study up before a Wildling says something like this to you:

In all seriousness, though, the guide lets you explore maps, characters, specific episodes, videos and appendices full of facts about gods, rebellions and historical tidbits.

It also features exclusive content, most of which can be shared across social sites.

The videos include interviews with the cast, crew and A Song of Ice and Fire author George R.R. Martin, who recently released a chapter from his new Game of Thrones book.

In addition to the interactive guide, HBO also revealed Tuesday that HBO2 will show all episodes of the three previous seasons in a row — twice — starting April 4 at 9:00 a.m. ET. The marathon showing will end April 6 at 9:00 p.m. ET, when the new season commences.
