Assassin Guild

Assassins Guilds were organized groups of Assassins based in cities across the globe. The guilds formed the basis of the Assassin Order's command structure after Altaïr Ibn-La'Ahad disbanded the Order from Masyaf in 1257, with each guild coming under the control of a Master Assassin.

During modern times, the Order seemed to have organized itself into smaller groups of Assassins per city, dropping the idea of complete guilds.

Guild management
The Assassin guilds recruited their members in a number of ways- in the city of Rome, for example, the guild recruited from the city's disaffected population; those who had suffered at the hands of the Templar House of Borgia flocked to the guild when approached by a member. Once members, recruits trained through experience; they would embark on actual missions across the globe and aid in the progression of the Order's goals. Communication both between and within the guilds was facilitated through use of pigeon coops.

Each guild provided its recruits with a wide array of weapons and armor qualities. These usually improved in step with the apprentice's rank; higher ranked Assassins would gain access to weapons such as the pistol and smoke bombs. Additionally, the number of ranks in a particular guild varied between cities; the guild in Rome, for example, only had ten ranks, whilst the guild in Constantinople had fifteen.

In Rome, the ranks progressed as follows:
 * 1) Recluta (Recruit)
 * 2) Servitore (Servent)
 * 3) Assistente (Assistant)
 * 4) Milite (Soldier)
 * 5) Discepolo (Disciple)
 * 6) Mercenario (Mercenary)
 * 7) Guerriero (Warrior)
 * 8) Veterano (Veteran)
 * 9) Maestro (Master)
 * 10) Assassino (Assassin)

Ceremony
"Laa shay'a waqui'n moutlaq bale kouloun moumkine. The wisdom of our Creed is revealed through these words. We work in the dark to serve the light. We are Assassins. Nothing is true, everything is permitted."

- Ezio Auditore during the ceremony.

Upon reaching the rank Assassino, an initiation ceremony would be held. In Rome, these ceremonies would take place within the Tiber Island headquarters. Following the ceremony, the Assassins would don the official garb of Order, similar in style to il Mentore Ezio Auditore da Firenze's.
