Amazon's much anticipated 'The Lord of the Rings' series has started fanning the flames on social media, teasing a map of Middle-earth and giving us tiny glimpse of the unique JRR Tolkien world created in the show.

'The Lord of the Rings' official Twitter teased fans on Monday with the first version of the Middle-earth map, leaving fans with more questions than answers.

The script of the $250 million deal show, which is in its earlier stages of production, has been kept highly secretive by the showrunners.

According to reports, the writer's room is kept under high security with the windows taped shut, and additionally, the actors and writers have to enter the vicinity after going through a fingerprint-based security system.

But one particular change in Tolkien's map was noticed, and this peculiar update confirms when the series takes place.

The region which was called Rohan back in the day under Gondorian rule is now replaced by the predating Calenardhon, which strongly suggests that the series is a prequel.

Rohan was founded hundreds of years before the birth of Aragorn, so him being the main focus of the show is definitely not happening.

Until Smeagol found the One Ring, it is said to have remained dormant from after Isildur died in the Second Age, so perhaps the series will focus on the events covered in 'The Fellowship of the Ring' movie's opening scene, with young Elrond, Isildur, and company. This would prove true reports that said the show had signed a deal to use “material” from Peter Jackson’s film series.

There is also the possibility that the show is just laying out the history of the world, and may not be directly referencing the show's time frame.

Amazon was lucky enough to get the rights to Tolkien's magnum opus, and they will be producing a multi-season show together with publisher HarperCollins, New Line Cinema and of course, J. R R Tolkien's Estate. The streaming giant has a lot riding on the show in the franchise’s Middle-Earth setting, with expectations that the budget could cross one billion dollars.

'The Lord of the Rings' series, which is said to release on Amazon Prime by 2021, has not set a premiere date. And with the series still in the early stages of production, the only concrete info we are likely to get about the show will be updates coming from the showrunners.
