1.What ever happened to Kar Vastor?
Kar Vastor was a Korrunai that Mace Windu encountered on his home planet. He was a powerful force sensitive who was not actually a dark sider but used the force for selfish reasons. I use selfish loosely because Vastor was a product of his environment. He saw his family murdered by off worlders and was left in the harsh jungles of Haruun Kal. In this situation no one lives but Vastor was able to survive for one year. He was very strong in the force and actually beat Mace Windu in combat. He is also like Mace Windu, one of the last survivors of the ghosh Windu. He was captured by Windu and arrested. He was taken to Coruscant to await trial. That is the last we heard from him.
Nick Rostu was another force sensitive Korrunai that Mace encountered on his mission to his home planet. He was a guide for Mace Windu into the jungles of Haruun Kal. Windu inducted him into the Grand Army of the Republic. I liked his character. He was spunky and very useful in a fight. He was severely wounded but survived. Mace later mentioned him in his archives and stated he was on Coruscant in a medical facility.
I hope someone brings them back.
