Coleman Kcaj was an Ongree Jedi Master who replaced Master Oppo Rancisis on the Jedi Council following his death on Saleucami. Kcaj was in the Temple when Order 66 was excecuted but his fate remains unknown.
Quoting Michael Kringe
Yeah, I remembered him. I guess he was the only left Jedi council member on Coruscant, when Mace and his friends died. There was a similar guy called Pablo Jill in episode 2, I think.
Yeah Shaak Ti was there to but she got away. I hope this guy died. In a way I think to many Jedi survived Order 66.
