Ethri is an energy that can be harnessed by Arkn to use their magic, known as Ethrial Manipulation. It can also occur naturally, due to The Source, and can be carried in a liquid form, known as Ethric Fluid. This liquid will leave behind a crystallized residue that is naturally charged with Ethri. This residue is known as Ethric Crystals and is formed from super-heated Ethric liquid. In addition, ancient super volcanoes of Ethri can be found, such as Mortavrest, these produce an Ethric steam that can act as a charge, and even power some tech in Mistria.


During the creation of .Mainframe a rebooted .reality core was used to create a connection between the base and the universe on top of it, alongside this, a split of the core was created to allow for the universe to be boxed in. This split core is was taken over by Fabras, and became the Heart of Ethri, known as The Source. Here, Fabras used the last of his power to create Tatsuonga, the Ethric Mind. Fullblood Arkn and Dekn (along with Halfbreed Dekn) all have a connection to the Tatsuonga, Arkn because of Ethri, and Dekn mentally, and are able to tap into its mind to create certain sigils.

The Ethric Mind and origin of Ethri is only known from scrolls and books written by Jacques, as the Source is inaccessible, with no known entrances.

Types of Ethric Crystals

  1. Naturally Ethric Crystals: Naturally charged but nonchargeable.
  2. Rethyc Crystals: Naturally empty but can be charged and recharged. Will break after extensive use.
  3. Nullithic Crystals: Crystals formed from Ethric Volcanoes that can not hold a charge or be charged.

Ethri as Blood

Arkn contain Ethri in their blood, which allows them to channel it naturally. The full extent of that can be found on the Arkn of Universe X page.
