Meet with Ratbag, who has a message for you.
Go to the meeting point, where you discover it's a trap. Of course it's a trap, this one set by your old friend Bruz.
He'll set his caragors and a few orcs on you. The Shadow Mount skill is extremely useful, even more so in conjunction with Dominate. Note also that you can Shadow Mount from the back of another caragor.
Between your blade, and their jaws, this one will be over before it's even begun.
And it turns out that's all there is to this one. Don't worry- plenty more Bruz left to come.
