Everyone is getting excited about "Game of Thrones" season 5. And to amp up the excitement, here are some new updates about the show.  

First off, two Sand sisters have already completed their scenes in Season 5. Watchers on The Wall reported that actresses Keisha Castle-Hughes and Jessica Henwick, who play the love children of the late Oberyn Martell, confirmed the news. Both actresses took to Twitter to share that filming is over for them. 

Castle-Hughes tweeted: "And that's a wrap for Obara Sand on @GameOfThrones season 5! 6 months, 3 countries, 200 hours flying & 2 incredible Sand Snake sisters." 

Likewise, Henwick tweeted: "And that's a wrap for me on @GameOfThrones! 5 months, 3 countries and 1 epic introduction to the Sand Snakes." 

Season 5 marks the introduction of the dangerous Sand sisters. This move was forced due to the death of their father at King's Landing. They come from the kingdom of Dorne, a kingdom ruled by House Martell.  

Castle-Hughes plays Obara Sand and she is the eldest daughter of Oberyn. She has a strong character and uses the whip as her weapon. She has a quick temper and has a fighter spirit. She prefers fighting over diplomacy. 

Henwick, meanwhile, portrays Nymeria Sand who plays a more important role than Obara in the grand scheme of things. Later, she will take a seat at the small council at King's Landing to replace her father. Nymeria wants revenge for the death of Oberyn and she will make sure that she exacts her revenge on the Lannisters. 

If that's not enough, fans should enjoy the newly released trailer for season 5. HBO launched a website called ThreeEyedRaven and there, a 10-second teaser video was uploaded. The teaser shows Arya Stark, but that's pretty much it.  

The teaser is definitely mysterious, but it looks like this is what HBO is trying to achieve. What's more mysterious is when one clicks on the three-eyed raven, it will ask, "How do you wish to receive The Sight?" They will have to choose between text message or Twitter. Movie News Guide is guessing that The Sight refers to the full trailer for season 5.
