Yukti cast

Yukti or Mahō is a cast native to nearly all of Eisea, and elsewhere on Zawādo in small communities. With 1.73 billion registered casters, it is by far the biggest cast in terms of practitioners, though not by area as the Easter cast.

History
It is widely accepted by the Magochronological community that Yukti and Vaudoux are the two oldest surviving casts, though which of the two is older is unclear as new discoveries continue pushing the dating back for both. Currently, the oldest confirmed evidence suggesting the presence of Yukti is a stone inscription in the southeastern walls of Mundeshwani Devi temple in southern Hidica, dated to approximately 5670 ln. The inscription contains a telling of a myth about Vishnu, and an offhanded mention of Vritra.

That aside, there does exist a much older unconfirmed piece of evidence for Yukti presence, prehistoric in fact: a swastika carved into mammoth ivory, found in western Eisea, dated to circa 15,000 ln. nearly triple the Mundeshwani inscriptions. This, however, has been met with debate, as it is unclear as to whether the swastika in question is a truly sanctogram or a decoration; or perhaps even a sanctogram to an earlier, extinct cast from which the swastika was inherited.
