Arcane

Arcane Magic is a form of magic that is different from the rest due to it being called the essence of magic itself, or the Earth itself.

The Beginning of the End
"See also: EoL:EP9 The Beginning of the End"In the backstory episode of The End of Lore, it shows Magmus Prism, one of the first known arcanes, fighting alongside his friends in a magical war between their city and another. Suddenly, his friend gets run over by a alicorn, its rider holding his sword above the boy's chest. The sword suddenly strikes down... Magmus is so enraged and distraught that when he screams, the whole battlefield "shatters" to pieces in glowing white light

Beggars Can't be Choosers
In a backstory episode for The End of Lore, an arcane witch named Wilhelmina Selvozark appears to Magmus one day, pretending to be a poor beggar, when she in fact only wished to steal his mana and magic. Upon realizing who he was, however, she introduced herself as who she truly was as well, and they became distant allies of sort from then on.

Arcana and the Infinity
In a backstory episode for The End of Lore, in parts of Journey to Lore, and mentioned briefly in Project Stigma, the arcana deck set forth decides upon the fates of certain groups of at the most 25 people per three century. Magmus was regarded as the Aeon (XX) of the tarot deck. In the episode, it shows the others receiving theirs as well.
