Your companions that survived the battle with the Sha of Doubt are now in the care of Binan Village, home to Pandaria's finest healers. It looks as though they shall recover their physical injuries.
The journey to Binan will take you up the Veiled Stair to the very doorstep of Kun-Lai Summit. I urge you to bring this missive to Mayor Bramblestaff in Binan Village. There, he can direct you to your companions.
I look forward to our paths crossing again.
