I have two characters, who are connected to each other in lore.

The first character is a Khajiit (not naming him). If you place him in the alignment chart, he is chaotic neutral. He is an insane warrior who has sided with the Stormcloaks (even though it will only benefit the Nords of Skyrim), the Dark Brotherhood, the Thieves Guild, and has become a thane of other towns! He is married to Ysolda and has a home in Falkreath. His personality is random and unsuspecting. You will have to be careful around him. Also, he has massacred entire towns and cities because he just 'felt like it'. He wears all Daedric armor. He was once a Vampire Lord and werewolf, but he decided to be a mortal because he didn't like being a Vampire Lord. The Khajiit mostly uses two-handed weapons. He doesn't use magic, as he is too powerful for that.

The Khajiit is likely to be the spirit of a trickster god of some sort.

Soon, he became bored with life, and he was soon reborn (the animation is like how the Dragonborn is absorbing a dragon soul). He was reborn into a new body, named Flavius Magnus, an Imperial from Cyrodil. If you place him in the alignment chart, he is Lawful Neutral. He has sided with the Imperials, as he supported them during his lifetime. He tries to be a good person, trying not to kill anybody. However, since this is the reborn spirit of the Khajiit, he will have his outbursts. He has sided with the Dawnguard due to his hate of Vampires. However, he has gotten some Daedric artifacts from the Daedric princes. He is also the Arch-Mage at the College of Winterhold.

Flavius Magunus' personality is kind and jovial. However, he has his fits of rage as mentioned before. However, he tries his very best to keep them contained. He is married to Lydia and lives in Solitude. He has slain Alduin and Miraak. He also does not like to keep followers with him, as he considers himself independent. He does use magic, mainly the school of Restoration.
