HBO Max unveiled a teaser trailer for its hugely anticipated 'Game of Thrones' prequel 'House of the Dragon' with an expansive cast at its European launch event on Tuesday, reports Variety.com. The American fantasy drama series 'Game of Thrones' acquired an international cult following after it ran for 73 episodes across eight seasons between 2011 and 2019.

'House of the Dragon', based on 'Fire & Blood', the 2018 novel of George R.R. Martin, is set 200 years prior to the events of 'Game of Thrones' and tells the story of the House Targaryen and the Targaryen civil war that became known as the 'Dance of the Dragons'. Martin, incidentally, is also the author of 'A Song of Ice and Fire' fantasy novels, which inspired the 'Game of Thrones' series.
