Corporal destruction
Corporal destruction is the most severe punishment that can be administered upon a person under the system of penalties governed by the Bureau of Punishment and Castigation (BPC). Punishments of similar seriousness but of lesser severity can include the permanent seizure of funds, property, or the person.
Public knowledge holds that corporal destruction results in the condemned person ceasing to exist in the Illuminatian realm. In reality, the administration of a corporal destruction penalty involves the condemned, after mild sedation, being unwittingly and secretively transported to Illuminatia's only penal colony on Supplicium Island, where the condemned person is permanently removed from outside society and is free to live the remainder of their natural life in the company of other condemned persons.
As such, capital punishment—strictly speaking—does not exist in Illuminatia, which is a position consistent with Illuminatian cultural values. While the public's understanding regarding the fate of those condemned to corporal destruction is limited to the readily-available appearance of the situation, members of the general public also have access to highly-detailed demographics data which provides a distinct lack of indication or record of any termination of life event related to any corporal destruction ceremony.
The process
Those who the BPC condemns to corporal destruction first endure a public corporal destruction ceremony, during which the public observes the destruction of the condemned person. The ceremony is usually carried out by administering a drug of a variety that renders the subject unconscious. All parties involved—including the condemned, the observers, and the administrators of the punishment—understand the drug will result in the condemned person ceasing to exist. The corporal destruction ceremony visibly results in the cessation of respiration and cardiac activity, including a stopping of the pulse. These corporal destruction ceremonies, in recent times, have been broadcast on select telekinephotography outlets known for these broadcasts, with ample warning to viewers relating to the potentially troubling nature of the broadcast.
After losing consciousness, the subject condemned to the corporal destruction ceremony is secretly transported to Supplicium Island, where they awake after several circadian units of deep sleep. The punished subject receives no briefing or information regarding their location and is not informed of the true nature of the punishment that was carried out upon them. The newly-arrived resident is normally released and allowed to regain consciousness alone in a remote, undeveloped location on the island. Upon waking, the condemned person discovers they are in possession of a portable package containing life-sustaining supplies.
After a short period of time, the condemned person is allowed to come into contact with an agent of the BPC's Supplicium Island squad, who officially informs the subject that they aren't dead after all and provides the subject with support that will allow the condemned person to establish a sustainable existence on the island. Generally, residents who arrive on the island after a corporal destruction ceremony acquire a new identity, although the establishment of an identity on the island is purely the choice of the condemned person and is not necessary. Oftentimes, subjects source materials that allow them to considerably alter their visual appearance, which can provide some comfort to the condemned in the event they come into contact with other condemned persons with whom they may have been previously acquainted in Illuminatian criminal society.
Consequences
Persons assessed the punishment of corporal destruction are allowed to live out the remainder of their natural lives with freedom of movement and action so long as they do not attempt to leave Supplicium Island or communicate with the outside world.
All residents of Supplicium Island are permanent residents. Residents are not allowed to interact with or communicate with the outside world in any way and are never provided with means for doing so. However, residents are free to interact amongst themselves and to cooperatively build societal structures, construct shelter and amenities, and share and trade in resources.
