Recently I was watching a American fantasy drama, a very popular television series "Game of thrones" which primere on HBO channel since 17 April 2011. This series is base on a single iron throne. Several royal families desire the iron throne to take control on westeros. Which is fill with amazing mystery, fantasy, and awesome vfx. This story start with king in the north "Ned Stark"  who rule over the north who has a beautiful wife, 2 kids, 2 daughter and 1 bastard kid. He has to send his bastard kid "John snow" to the wall. Because all bastard are send their to spend their entire life to protect North and other region from wildlings and death. Death is a mysterious creature who live after death of anything which can be end by only fire and dragon glass. On the other side the recent king in westeros "Robert Berathian" who is a old friend of Ned stark come in North with a proposal of his kid "Joffry berathian"  with Ned stark elder daughter "Sansa stark" for converts their friendship in relation.

This is the throne
Which several families want. 

While this happening,  on foreign region velyres targaryen sold off his sister to khal drogo(dothraki lord)  to marry him in exchange of his large army to attack on westeros to get back his father(former king in westeros) throne and to rule. From now on it'll become so awesome, curious story. With dragon, lot of things happen with Ned's kids and daughter. Sorry, I can't tell you everything, but I strongly recommend you to watch.
