If you are a Star Wars fan you are familiar with the Sith. Aside from the fact that the Sith are the antagonist of the series, there are also some interesting facts about them.
To start off, since the Sith are not welcome wherever they go, they are able to hide their presence. Force Stealth is the name of this ability. Sheev Palpatine (Darth Sidius) used this ability on Star Wars saga – Episodes I through III when he hid the fact that he had contact with the Force from all Jedi around him.
Kylo Ren is not a Sith. This was confirmed during one of the interviews with Director J. J. Abrams.
They are able to peek into the future through the ability of Force Visions. This ability may be perceived either a blessing or a curse. This ability was used by Anakin when he saw Padme dying, which drove him to join the Sith.
The lightsabers of Siths are made from bleeding kyber crystals. Kyber crystals were natural crystals that each Jedi has chosen to use when building their lightsaber. The Sith only use kyber crystals that belonged to slain Jedi which gives it the bleeding red color.
The Sith has the ability to transfer their souls to another person’s body and taking hold on it. This is called Transfer Essence. The Sith used Transfer Essence to cheat death many times.
Darth Maul is the only Sith Apprentice to have ever left the Sith. Darth Maul appeared to die in the Phantom Menace but in truth he was able to survive his encounter with Qui-Gon Jinn and Obi-Wan Kenobi. Thinking that Darth Maul is dead, Darth Sidious took Count Dooku as his new Apprentice which makes Darth Maul the only known Sith Apprentice who survived.
The Sith has the ability to choke someone to death without even having to hold him. Force Grip is the name of this ability and is seen being used by Darth Vader many times in the series. When Count Dooku fought against Obi-Wan Kenobi in Revenge of the Sith, he was also seen using the Force Grip.
Darth Maul is not the first user of a double-bladed lightsaber unlike what most people know. Exar Kun was the first wielder of this dangerous weapon. No one else aside from them has been known to wield a double-bladed lightsaber.
The Sith are not capable of becoming Force ghosts. This is the reason why they are obsessed over lengthening their life and even immortality.
The Death Star was created based on the ancient Sith superweapons. The Death Star is an extremely powerful weapon since it gets its energy from a giant kyber crystal.
Lastly, the base of the Jedi Temple on Coruscant is a Sith Shrine. Unlike other Jedi Temples, it is a symbol of the Jedi victory over the Sith.
