- — Bill on the Gear's fears of Polyps
Bill William Taylor was a Gear in the Coalition of Ordered Goverments, joining for Operation: Hollow Storm. He took place in the charge, and was one of the few to survive the charge to Landown. He also participated in the defending of Jacinto before having to evacuate to Anvil Gate following Jacinto's sinking. He was part of the COG forces during the Battle of Azura. He began to develop Rustlung while at Azura, and assisted in killing the Lambent for Delta. When Adam Fenix activated the weapon, Bill had enough Imulsion in his system to be effected. He, along with hundreds of Humans, all of the Lambent and most of the remaining Locust was killed by the weapon. He was at first awed by the light, until he began to deteriorate.
