Nihilus

Nihilus, Darth Nihilus VII or Emperor Nihilus I is the current Emperor of the Sith Empire, a title he claimed when he killed Darth Malak I, who was emperor before him, in a duel. 
Nihilus renamed his house upon becoming the Darth, which is an uncommon thing to do, and infact has only been done a few times before. Previously it was known as House Jivaan, but is now known, of course, as House Nihilus . Nihilus was adopted into House Pivaan, and is considered one of the most powerful psionics in existence, being one of the only regesitered Class D Level 5 psionics to have ever lived and believed a master of both Makashi  and Djem So Lightsaber styles. 
==History==
Only a few people know Nihilus from before he became emperor, and they keep what they know to themselves. Nihilus had all records of his past burried, the only thing that is widely known about him is that he was adopted into house Pivaan, and of course everyone knows how he became emperor by slaying former emperor Malak. He doesn't seem interested in politics, and probably had other reasons for wanting to become emperor, seeing as he has hardly changed a thing since Malak's reign. 
==Personality==
Nihilus is, despite being emperor, not a public figure at all, and his personality remains as shrouded in mystery as the rest of his being. He is very intimidating however, and doesn't tollerate failure and has no regard for life or other people at all, not even members of his own house, or people who have worked for him for years. He seems quite devoid of emotions. 
==Description==
Nihilus stands 190 cm, and with that just above average. He has a powerful frame and his species is assumed to be Alamari/human cross-over. He is never seen in public without his skeletal mask and his black robes. At the time when he killed Malak, he wielded a red lightsaber.
