Guardians of the Night

The Guardians of the Night are a group of elite Duelists within the ''Yu-Gi-Oh! Battle Realms ''anime. They have an agenda of finding and collecting the "Legendary Cards ", cards of unlimited power that are the key to the power of "Endless Night". They are governed by the Transcendant Three, three extremely powerful Duelists who possess dark powers.

The entire organization appear during the World Duel Championship even though they are not enrolled in the tournament. They act as main antagonists during this arc of the story.

Etymology
Each member of the organization has a name that reflects the theme of their deck or in the case of the triumvirate their names reflect an aspect of the the opposition between Ideal and Nothingness that is governed by Chaos.

Abilities
During the WDC every member of the Guardians of the Night show that they can use an array of strange abilities. The first is that they have no need of a Duel Gazer in order to see Duel Monsters, instead one or both of their eyes glow or change colour (or both).

The second of their abilities is the power to initiate what Reaper calls a "Death Match", in other words a duel where damage is inflicted for real and the loser can be badly hurt, in a coma or even die. In order to activate this power the Guardians of the Night throw a field spell card covered in a dark aura on the floor which then creates a dark sphere engulfing the Duelists and any spectators nearby.

The third ability is a form of teleportation by transforming into shadows, this power is not explained in the anime and is used mainly for retreating after a Duel.

Chaos, the head of the triumvirate has shown the ability to become shadows and move about in this shadowy form, he can even enter highly secure areas that should be otherwise inaccessible.

Infinity, the second in command of the organization is able to transform into a white luminous figure and teleport or go through objects.

Zero, the third member of the triumvirate has shown the ability to manipulate others, people who are possessed by him have bright purple eyes (like Zero).

History
The Guardians of the Night were created by the Transcendant Three in order to serve an ancient evil. Though not much of their history is known it seems that all members did not join of their free will and probably died in a past life to be reborn as the dark duelists they are today.
