Apostle

About
An Apostle (sometimes also referred to as Acolytes) is a mortal that has been granted eternal youth by a Dark Lord in exchange for servitude.

An Apostle is created via a blood pact, the prospective Apostle drinks the blood of the Dark Lord. In exchange for pledging allegiance to a Dark Lord, the Apostles receive eternal youth and enhanced power. They do not receive the Invincibility Field though, and can be killed. The species of the Apostle is also of no concern, the Dark Lord can share their blood with any creature and contract it, be it Gal Monsters, Haniwa  or even Insects.

The Apostle is unable to resist any order given to them by their master, this is a similar method to the blood control that the Demon King uses to command Dark Lords.

Typically, their combat power is enhanced far beyond that of a regular member of their species, and they often serve military purposes, usually becoming subcommanders for their master, commanding Monster Armies if it is required. Though in some circumstances, mental power or other abilities inherent in the individual are enhanced.

Unlike the Dark Lords, there is no limit to how many Apostles there can be. The Dark Lord is free to contract as many people as he or she likes, but there is a cost. Because the Apostles draw their power directly from the Blood Soul of the Dark Lord, the more apostles there are, the weaker the Dark Lord becomes and the more difficult it becomes to control each Apostle since the blood is spread thin amongst the minions. Dark Lords can revert their Apostles back to mortality at will.

When their master Dark Lord dies, the Apostle can walk free. However, if another person consumes the Demonic Blood Soul and becomes a new Dark Lord, that person inherits the Apostles of the predecessor. This is because the binding pact is not technically with the Dark Lord itself, but the Blood Soul. If the Blood Soul is formatted by the Demon King, or simply lost, the Apostles are freed from the command of anyone and are allowed to keep their enhanced abilites.

Lesser Apostles are individuals who are working with Dark Lords under good faith, no blood pact. These individuals that do not make the blood pact do not receive any of the benefits that a standard Apostle would. Apostles are typically used as combat personnel for the Dark Lord, so they don't have to dirty their own hands. Sometimes they're made to take care of the Dark Lord and his properties, the Maid Apostles of Kesselring tend to him and his estate.

Sometimes they're just made to be pets, Kaybnyan and Kaybwan fit this role.
