A former newspaper editor at the Gotham Gazette in his 40s, Edward Nashton was in charge of all the puzzles and games that went into the paper every week. After reports of his puzzles being too hard for the common reader to solve Nashton was fired from his post and left broken but determined to find someone to solve what he thought were perfectly crafted puzzles. His obsession to get his questions answered can either make Nashton an incredibly dangerous character or a blundering buffoon begging someone to give him that relief.
