Throughout history, in the advanced realms of Mysticism, 'support spirits' have never been a rare existence. In fact, they are widely useful, highly functional, diligent, and very cost-effective, thus they have always remained enduring.
Apprenticed to both the all-systems Magic Instructor Ana Ta Lasha and the Grand Astrologist Diana A. Achizolti, two ladies who possess many excellent traits such as strength, wealth, and solitude (though Diana is no longer solitary now), Double Leaf naturally knows what a guardian spirit really is. In fact, she has encountered quite a few support spirits during the more than half a year she has been into this game.
For the simplest example, most standalone Mage Towers have a tower spirit, and these 'tower spirits' are a type of support spirit.
During Double Leaf's studies with Ana, she often saw the tower spirit named [True Crimson Klausel V. Xutalian Shuvazer] in the latter's Mage Tower.
