HBO previewed a 15-minute teaser for their upcoming fantasy series “Game of Thrones” over the weekend.

The series is based on the “A song of Ice and Fire”, which is a series of novels by George R.R. Martin. The drama charts politics, magic and wars over the Iron Throne, which is the highest seat in the kingdom’s capital of King’s Landing.

HBO is hoping to attract both fantasy fanatics as well as a main stream audience that became huge fans of the “Lord of the Rings” trilogy.

The ten-episode full series will debut on April 17th and viewers are being warned there are some graphic images of violence involved.
