How many Black Knights (Black Wings Generals) are there really?

If I've been doing my research correctly, the Black Mage has 7 chairs in his sanctum, representing 7 generals (as most likely the Black Mage has a throne of his own, and can communicate telepathically), or 6 Generals and the Black Mage himself.

So far, I know of four (note, any names and/or titles are madeup, bear with me):

Valfar the Demon Slayer
Orca the Black Sky
Von Leon the Volcanic Darkness
Akhyrum the Fang of Darkness


I also believe that Eleanor the Black Witch is at least up there with Orca in rank, or is her second-in-command.

Remember, technically Orca survived the battle against Mercedes (but whether she survived the Black Mage's anger is another story). Akhyrum is in the past trying to revive the Black Mage or his generals (where we're here to thwart his attempt).

Von Leon is slain by the bequest of his wife, so he's marked canonically dead after his encounter.

Valfar defected to the Resistance, due to his family being killed by the Black Wings (and we can somewhat assume he is/was a resident of Edelstein at some point.

Eleanor is slain by the Cygnus Knights, or at least escapes (and again, like with Orca, she may not live through the Black Mage's wrath).

Baroq and Francis, both underlings of Eleanor (and perhaps Orca as well) are eliminated (I believe Baroq is slain by Aran, canonically, and Francis I think is disposed of by Orca or Black Mage).

So do I have this right, save the parts I made up myself?
