What is the assassin's creed?

From The Assassins Creed wiki:

The Assassin's Creed is the code and guiding philosophy of the Assassin Order, upheld from the Third Crusade, until modern days. It restricts unnecessary slaughter of innocents, preserves the reputation of oneself and of the Order, and is meant to create peace, not only within the world, but within the individual.

The three main rules (tenets) of the creed are (also from the wiki):

  1. Stay your blade from the flesh of an innocent
  2. Hide in plain sight
  3. Never compromise the Brotherhood

The Maxim is another part of the creed (wiki as well):

Nothing is true; everything is permitted


"Laa shay'a waqi'un mutlaq bale kouloun mumkin."
("Nothing is true, everything is permitted" in Arabic)
-- The Creed's maxim

The Assassin's Creed is the code and guiding philosophy of the Assassin Order. It restricts unnecessary slaughter of innocents, preserves the reputation of oneself and of the Order, and is meant to create peace, not only within the world, but within the individual.

The Creed mainly emphasizes three simple, moral tenets that focus on ensuring a successful mission, mastery of emotions, and the safety of the Brotherhood.

  1. "Stay your blade from the flesh of an innocent."
  2. "Hide in plain sight, be one with the crowd."
  3. "Never compromise the Brotherhood."
