Alignments are in-game groupings or categories that shows part of a Servant's Personality. Before The Garden of sinners - the Garden of Order, Alignments were considered to be just flavor text in the game, part of every Servant's Lore. The Garden of sinners - the Garden of Order introduced a Mission System which tasked players with defeating certain Servants with certain Alignments. This mechanic has been repeated in future Mission Events, as well as Master Missions.
Alignment is defined in two parts:
The Axiomatic Axis: Lawful (秩序) - Neutral (中立) - Chaotic (混沌)
The Moral Axis: Good (善) - Balanced (中庸) - Evil (惡)
The exceptional cases are the "Madness" (狂) Alignment which is only for Berserkers who lost all their sanity. (eg : Heracles and Lancelot), the "Bride" (花嫁) Alignment for Nero Claudius (Bride) and also the "Summer" (夏) Alignment for Tamamo-no-Mae (Lancer).
