How many members of the Jedi Order formally joined the Separatists?
In Canon, the Confederacy of Independent Systems had several former Jedi serving it in one capacity or another, the most prominent of whom was Count <PERSON> who formally left the Jedi Order then later publicly joined and ran the CIS. <PERSON> trained a former Jedi Padawan, <PERSON> as a Sith Assassin, and Jedi General <PERSON> tried to sabotage the Jedi Order from within during the Clone Wars.
However out of all of these, only <PERSON> actually formally left the Jedi Order to join the CIS; <PERSON> was being trained as a Padawan away from the Jedi Temple and when her master was killed her training effectively ended on its own, and <PERSON> never formally resigned from the Jedi Order (and may never have actually formally joined the CIS either).
In Legends, several more former Jedi served the CIS as well:
* <PERSON> although she never formally left the Jedi Order.
And then the remaining members of Count <PERSON>'s Dark Acolytes:
* <PERSON> who was corrupted by <PERSON> and then led the Dark Acolytes.
* <PERSON> and two other unnamed Jedi who left the Order to form the Jensaarai.
* <PERSON> who refused to return to the Order during the outbreak of the Clone Wars and then was corrupted by <PERSON>.
* <PERSON> who was corrupted by Count <PERSON> and whose turn to the Dark side was known to the Order.
Although neither <PERSON> nor <PERSON> formally left the Order, nor <PERSON>, it could be argued that the members of the Dark Acolytes essentially did even if they were turned to the Dark Side first by Count <PERSON>. My question therefore is, in addition to the above, did any other Jedi, in Legends or Canon, actually leave the Order, either before or during the Clone Wars, and join the CIS?
Although answers can include Jedi who at one point or another helped the CIS (i.e. <PERSON> who (in Legends) was corrupted by <PERSON> before being redeemed later on), I am really looking for Jedi (whether Padawans, Knights, or Masters) who permanently left the Order and then chose to fight for, or at least contribute to in some capacity, the Separatist Cause. 503
