There are a few people I could/would nominate, but not sure if I can nominate more than one.
But I would like to nominate
Darth Strosius
!
Even before I made a character on Chaos, I followed along with his character's story and development and I really enjoyed what direction his Sith boy went. Writing with Strosius has been one hell of an amazing adventure; he's so sassy that you just never know what's going to happen next, but at the same time he's devoted to his cause and fearless and frankly, a very good teacher! I just love how complex and unique he is amongst other Sith, especially with his zealous nature. Not very many Sith would have the balls to face two Dark Lords in combat without an ounce of fear, and even be willing to face the Emperor, consequences be damned, because of how deeply he believes in his purpose and his visions and goals. Definitely can't wait to see more of his story and how it continues to unfold.
