It is very sad news that you bring. But I do not believe Hemlocke is dead. He is a stubborn SOB who would refuse to die anyway. And if he is truly dead, we can always try to revive him with Liberty ale. Truly, Rogues are strange people.
Or Revenant is just lying.
Which makes me think of a new project: Project Headpat. I will put out a notice for people to find Hemlocke and give him a headpat. If he faked his death and is indeed the right Hemlocke, he will be very angry if you pat him on the head. Then you will know the right Hemlocke has been found.
