Travel to Blackrock Mountain and use the Extra-Dimensional Ghost Revealer to find Bodley near Blackrock Spire.
So we need to recover the rest of the medallion? Finding Bodley's going to be a bit of a headache. He went back to Blackrock Mountain to attempt to re-enter Blackrock Spire and never came back.
I'd suggest taking the goblin's ghost revealing device with you, as I fear the worst might have happened.
