So it came as a shock last week whenWarner Bros. announced they aredeveloping a movieset in theGame of Thronesuniverse.

Luckily, there is a particularly notable event inGame of Throneshistory that would make for an excellent movie.

The Doom of Valyria is one of the most important events in theA Song of Ice and Fireseries.

Valyria is inspired by Rome, a huge empire that spanned most of Essos and lasted for 5000 years.

Their reign was unimpeachable,until its sudden collapse.

Despite ruling for 5000 years, Valyria fell in less than a day.

Fire and blood and a lot of wigs.

What Caused the Doom?

Nine noble families fight for control over the lands of Westeros while an ancient enemy returns after being dormant for millennia.

Its possible that internal conflict led to the assassination of mages integral to the upkeep of Valyria.

However, there is another possible explanation that involves an iconic faction from the mainline series.

Another big source of speculation comes from the Faceless Men.

While the Targaryens are the most powerful House in Westeros, theywere a relatively minor family in Valyria.

This would add a hopeful note to an otherwise dour story of destruction and death.

The film could even be accessible to viewers who didnt enjoyGame of Thrones, given its fantastical setting.

It offers a unique tale that simultaneously ties into the main story without depending on pre-existing material.
