[Source] Thunder is a crossbowman of the Fallen Knights during the Hearts of Stone expansion for The Witcher 3: Wild Hunt. At the command of Ulrich he worked as a fisstech dealer. Thunder, however, often snatches goods for his personal use, and under its influence, writes poems. When the Grand Master learned about this he sent a threatening letter to him with warning that if he repeats it, he will follow the suad of Peter Nayhaer to Deadwight Wood.
