Character from He Who Fights with Monsters by Shirtaloon
An arrogant noble's son who chased power so recklessly he lost his soul to the Builder — and the hollow vampire that replaced him might actually be a better person.
Thadwick is arrogant, petty, not particularly bright, and convinced he is Jason's arch-nemesis — a delusion Jason finds more annoying than threatening. Son of Beaufort and Thalia Mercer, nephew of the Duke of Greenstone, he used family connections to coast through the Adventure Society and bullied teammates like Neil into compliance. His desperation for power led him to be implanted with a Builder Star Seed. After being freed, he sought reimplantation — volunteering to become a vessel for the Builder itself. When the Builder left, Thadwick's soul was gone. The energy vampire that inherited his body and memories ironically developed a sense of ethics that the original Thadwick never had, calling out his former self's selfishness and treachery.
Originally a typical Greenstone noble's son — well-dressed, entitled bearing. After becoming an energy vampire, his appearance shifted to something predatory and wrong, the original Thadwick's features worn like an ill-fitting mask.
