Minions
Minions are familiars subdued to Master's will. They will execute their master's orders without anything in return. Most minions are weak and low intelligence creatures. Mighty creatures usually have minions (Demons, Vampires, Witches). As their mind is fully controlled by the master, minions wouln't retreat, but under master's order.

Vampire's minions
Since antiquity, vampires have manipulated human's mind in order to create slaves and servants. Even though ghuls  were a sufficient source of mindless workers, they are clumsy and keep vampire's weaks and human's weaks. Vampires developed mind control in order to slave humans. Mankind can work during sunlight and, overall, they provide blood.

Ingame vampire's minios are used to get a constant income of blood. Acquiring them requires a fee and certain perception level. They can also be freed. Some minions cannot be foun in bazaar. These minions have additional effects.
