The Brotherhood's induction — Basim becoming one of the Hidden Ones, the precursor organization to the Assassins proper. The shadows are both tactical and ideological: the Hidden Ones operate without visibility because visibility is vulnerability, because the Order of the Ancients controls the visible world and the only way to work against that control is from beneath it.

Mirage is a deliberate return to the series' original register — smaller scale, more focused, the parkour and the assassination rather than the open-world RPG. The Hidden Ones working in shadows is the game's design philosophy applied as narrative: this is not a story about the world-historical sweep of Basim's eventual destiny. It is a story about a young man learning what the shadows require.
