Potential Space Marines are usually, but not always, recruited from the worlds where a Chapter has established its fortress-monastery, although some Chapters are known to recruit from a collection of different worlds in an area of space that they protect or frequent. Recruiting methods vary from Chapter to Chapter. Some select their neophytes from feral tribes roaming the surface of inhospitable worlds, while others draw upon eager volunteers who have been groomed from birth to become an Astartes. Still others watch and kidnap potential warriors, turning them into Astartes whether they will it or not. Whatever the method, all Space Marine Chapters will only accept those who successfully pass the grueling initiation trials and prove themselves worthy of becoming a Space Marine.Ī Primaris Space Marine Intercessor of the Ultramarines Chapter in Mark X Tacticus Pattern Power Armour wielding a Mark II Cawl Pattern Bolt Rifle.
