Darth Krayken, formally known as Jedi Master Rogan Maximus, is a Sith Lord born and raised in The Old Republic on the planet Alderaan. As a child, he grew up lonely; every time he tried to make friends or join a group, he was rejected; even his family distanced themselves from him. However, he didn't let that stop him. He was quite smart and persistent when it came to his work. Rogan grew up and achieved many successes in his life. One day, a travelling Jedi named Darrick Mugba sensed that Rogan was Force-sensitive and took him to Tython to join the Jedi Order as a young Padawan. Rogan's master was Zun Coven, a Twi'lek Jedi Master who held a seat on the Jedi Council. Maximus quickly learned the ways of the Jedi and quickly became a Jedi Knight, and was soon given his own Padawan to train, Krystah Valorous; a young human girl. Many years later, Krystah finally passed her training, becoming a Jedi Knight, which granted Rogan the rank of Master. Rogan felt that he had proven himself and requested that he have a place on the Council, but he was refused. Maximus was puzzled by this and asked why, but his question was ignored. After this encounter, Rogan became angry and cold. Everywhere he went, he thought the Jedi were selfish and self-serving. Everyone made fun of him, just as they had when he was a child. One day Rogan decided to take some time off and travelled to the planet Korriban; something was calling him there. When he landed there, he saw beautiful buildings that he had never seen before. Rogan decided to look around these buildings, and soon he found himself face-to-face with a woman. She told Rogan that she was a Sith named Darth Zhaph and that she was a Sith pureblood. Rogan, who was trained in the ways of the Jedi, ignited his green lightsaber and was ready to defend himself. The woman laughed and approached Rogan to tell him that she did not want to fight but was giving him a choice. Rogan hesitantly deactivated his saber and listened. Zhaph said she belonged to the Sith Empire led by Naga Sadow and wanted to strengthen the order by recruiting more Sith. She sensed that Rogan was a powerful Force user and knew about how the Jedi treated him. "My faith lies with the order," Rogan remarks. "It's what I've learned and what I grew up with." Zhaph agreed, but she could sense the hesitation and confusion in his voice. Rogan was torn; what should he do? He could stay with the Jedi and always feel inferior, or he could leave his teachings behind and venture into the unknown. Rogan stood up and told Zhaph that he'd have to reconsider. Zhaph smiled, but the smile had a sinister meaning. Rogan flew back to Tython and began to think about it. He kept the encounter to himself, not wanting the others to know about it in case they tried to force him elsewhere. Rogan asked the Council many questions about the Jedi and the Sith, but all his questions were either answered vaguely or they were simply ignored. Rogan had had enough. He was sick of being treated like a child. He was a Jedi Master and wanted to be treated as such, so he flew back to Korriban and told Zhaph that he had thought over her offer and decided to accept it. He was ready to join the Sith. Zhaph smiled and took him to her ship, in which she flew to the planet Dromund Kaas. This dark planet is nothing Rogan had ever seen before; it truly amazed him. Rogan could literally feel the power that the planet was emitting. Zhaph stated that she would train Rogan to embrace his power and, until he was ready to reveal himself, that he should not attract suspicion in the Jedi order and act as a spy. Rogan agreed to this, and so began his Sith training. Eventually, after many months of vigorous training and spying, Rogan was ready to reveal himself. Zhaph was impressed. Even Naga Sadow had heard of Rogan. Naga himself came to meet Rogan and dubbed him Darth Krayken. The now Darth Krayken travels back to Tython and approaches his former master, who welcomes him with a smile, and apologises. With a confused look, Zun replies, "Whatever for?" "This," replies Krayken before igniting his blade into the chest of his master. A single tear left the eye of Krayken that day, as the sad and disappointed face of his master arose. Zun's lifeless corpse fell before Krayken, and the other Jedi looked on in horror before quickly igniting their blades to charge Krayken. Krayken fought hard, killing a few Jedi before they were ordered to stop by one of the Council members. They approached him and said, "Rogan, what is the meaning of this? Why have you killed so many Jedi? This is not the way."Krayken Scoffed, "For too long, the Jedi treated me like a mere child." The Council member replied, "But you are a Jedi Master." Krayken laughed, "Not anymore, for now, I am a Sith Lord. I...am Darth Krayken."
