Originally a member of the now decimated Tra'Kelv clan, Yondar Tra'Kelv evaded assassins and was led by Kian Tra'Kelv through the Force to the Jedi Remnant. There he joined and eventually became a Jedi Master on the Remnant Council. He still loves his light whip.
If you look at my other Star Wars minifigures, or if you have been on long enough and following me long enough to remember, you'll see Yondar Tra'Kelv, Force using Mandalorian of Yoda's species. When making the Jedi Remnant's council I decided I wanted to have a familiar face, and someone from the Tra'Kelv clan. Originally it was going to be Tallisibeth Skirata, married to Zack Skirata who use to be Zack Tra'Kelv before being adopted by Ordo Skirata. Then I added Yondar. Then, because it didn't fit with the story, as Cody Shan already knew Tallisibeth and Zack yet did not know the Republic or Jedi Remnants location, I scratched that and Yondar became the only Tra'Kelv on the council.
