IIRC, there were seven of them seated around that table, and all of the faces we saw were male. They could very well be Cowled Wizards, except that the Cowls have no link with Bhaal (that we know of, anyway), and their disquiet/fear/hostility from Gorion's Ward becoming too powerful would only make sense IF Gorion's Ward is a caster of Wizard spells--which He/She frequently isn't.

Priests of Bhaal? More likely. They don't even have to be connected with the Five at all--perhaps they're working against the Five, and hope to gain favor at Bhaal's rising by being in charge of the ritual exectution of his children. If I were any stupid enough to be working against Gorion's Ward, I'd be peeing my pants, too. The guys who made the end movie probably made the dudes look more like the Cowled Wizards in order to make you cower in fear (yeah, right) that the Cowls were plotting their revenge.
