Mandalore

Captain Tezla is in charge of protecting Mandalore. Mandalore is occupied by the Sith Empire, it is also where Darth Leviathan was born before he used Jango Fett's clones to gain the ability to cheat death. By using the force to switch his conscious between different bodies every time he died, the first occurence of this was after the Mandalorian Wars when he was killed by Darth Nihilus. However Leviathan lost his memory each time, so he eventually found out that by using clones, he could practically save his memory, so his memory goes back to the clone wars, when he first discovered this.
