There's at least 4: Nazzrakin, Coril, Nayadra and Arjen. Actually 7, if you include Revaethan, Jekaena and Carrow.
Well, I'm not counting our allies
But from this statement
"Shut up, Coril! We don't have time for this. Nayadra, help Arjen deal with the interlopers. The rest of you with me..."
It sounds like there's just the two.
