The Time Strain Particle, found in the brain of just one in three billion humanoid life-forms across time and space. This particle manifests itself in the late childhood and early teens and grants its possessor an unveiling of sorts, of the mysteries of time. The detection of the particle is the single means of selection to the Order of the Writers of Ages and instigates a series of events, which bring the subject to the Expanse, and put him into service as a Chronicle of the Order. To retrieve the subject, the Sirdar or his representative presents himself to the parents/guardians of the subject and informs them of the uniqueness of their child and that they are urged to surrender their child to the service of the order. Regardless of the choice of the parents, morality not being a factor, the child is taken to the Place of the writers, written out of his/her personal timeline, and elevated to chronicle status.
