Realiment

Realiments are shards or crystals that hold a Meta's true form. These shards are stored somewhere on or in the Metas chosen body, and make up that Metas essence. If they are destroyed, removed or damaged, the Meta will receive irreparable damage.

Mechanics
Realiments store mana inside them, and possess the unique ability to release that mana without excess left over. This mana regenerates over time, though it can regenerate faster with exposure to whatever the Realiment is. Metas are only made up of their Realiment, everything else is just a construct of Light. If a meta takes too much damage, however, this form dissipates, leaving the Realiment behind. It's also possible for a Realiment to change to a Fixspect over time if it belongs to a Spirit or Sponsor.

Whenever two Realiments clash, they combine into a new one that takes properties from both. This mechanic applies to everything, including Linking, Fated and Spirits. The combination of Realiments has resulted in the development of and endless amount of possibility.

If a Realiment is ever destroyed, the Meta's chosen body can never return, but the shards can still be used. These shards are extremely useful, but significantly less powerful than the original power of the Meta. If the damage is particularly bad, the shards will become dormant and inactive.
