"Ah you have seen through my ruse" Phalius says, improvising quickly, "We are in fact servants of Azarr Kul, he sent us here instead of hobgoblins to infiltrate Drellin's ferry. I could not tell you for security reasons, so I needed to find out if we would be challenged on the way to Drellin's Ferry, however I tell you now, as I realize that surely you must be among his most trusted. So tell me how the route is guarded, and why not lie down, you're bleeding, take off your armor and I'll heal you."
