Jon Zimmerman

Jon Zimmerman was the mayor of Adytum, person who invited the Regulators to help keep the peace.

He hated the Blades, as, apparently, they were responsible for the death of his son, who lived outside the Adytum. He died from the hands of the Regulators, during an attempt to see his father.

Jon Zimmerman was executed by a Regulator guard during the Blades' attack on Adytum in 2162.
