Clone wars season 5 finale question?

[ssgt splatter]

This may seem silly to ask but I can't find this anywhere on the Internet. Does anyone know what those strange jedi are with dual bladed yellow light sabers are? They don't look like normal jedi.

I'm typing this from my iPad right now and I can't leave a link to the video for some reason so just google "tcw seasone 5 finale trailer"

I'm can't believe I'm typing this, as much as I hold that show in low regard, I may know the answer to your question

Spoiler

Ok in recent episodes, someone had planted a bomb in the Jedi temple which Anikin and Asoka had captured a civilian who was responsible for it. Tension has been risen that people want the war asap and they are starting to mistrust the Jedi as they longer view them as peacekeeper they once were.
In today episode, that civilian reveal that the mastermind of it all is in fact a Jedi there are those who wanted to end the clone war now. Granted that woman said it was a single Jedi well one who taught her how to make a bomb but watching that season final trailer, I can guess it's a group of Jedi that are involve, not a single member. Also they are the ones who are weilding the yellow lightsaber well I'm guessing.
