The Blue Tactician and the White Mage

Details, details. I know why you're here.

Another piece of the puzzle, maybe you're curious.

But who am I? And what are you?

Another Riddle:

The Blue Tactician and the White Mage

The White Mage, a being of immense intellect, creates life.

Born from her memories, is the Blue Tactician, her daughter in both mind and spirit.

Sitting ever so slightly above the ground, as they enjoy their time together before her task is to be completed, playing chess.

Her daughter is to act as Durandal, an ally to a great warrior in green. His sword, and his shield.

Even without a form of her own, she exists. Beckoning to his mind, giving him guidance. 

Their plans set, they play, moving pieces against each other, ever in a standing war to dominate the board. Swiftly do they act, many of their warriors fall to each other. 

The White Mage, confident in her abilities, questions her daughter’s resolve. The Blue Tactician ever so slightly wins, if only for that moment of contention.

At the end of their game, her first words were uttered in a foreign tongue, spoken by both and understood only when said aloud. Those beside her name.

What is the blue tactician’s name? And what did she say as they left their game, before she was to join her green warrior against a greater evil?

This truth is soon to be spoken.
