The Enforcers are a type of Executioner created by Luther Lansfeld. While the Proclaimers are simply messengers, the Enforcers do all the real work, eradicating anything and everything that gets in their way. They come in many sizes, ranging from as small as a human, to as large as a Federation battleship.
The Enforcers were the initial force used to purge the Milky Way galaxy of the corrupt data. Most of them immediatly went after Federation Stations, and started destroying planets all over the place.
After the party started to resist the Enforcers, Luther unleashed an upgrade, the Convictor.
A type of Executioner that specializes in destruction. Apparently, an Enforcer isn't a single, specific type of Executioner, but rather one of a group of Executioners that has been given a specific mission to perform. Enforcers come in an incredible range of sizes, with lengths ranging from several meters to several thousand kilometers.
