Chiromata

A Chiromata is the physical embodiment of Mera.

Overview
Unlike the base four Mata, a Chiromata is formed from essence itself, a material that should rightfully not exist in any physical form. Thus, it expresses itself a life that should not exist. Like any physical form of Mera, a Chiromata is burdened with an insatiable desire to consume the world around it from the inside, corrupting lives until they too become Mera's form.

Birth, Death, and Resurrection
When a Belladon is killed before its life can fulfill its purpose, it's debt remains paradoxically unpaid. The essence that returns to the void is not of equal value to the essence that left, as some of that essence's value has been stolen by the world that killed it. This essence then manifests into a new being, one that seeks to claim its value back from the world and will stop at nothing to do just that. Crucially though, this essence never has the chance to form into any of the elements, and thus will remain tied intrinsically to the entire plane of existence.

This form has two eventual ends.
 * The form consumes the entire plane. In an attempt to reclaim the lost value of the essence, the life will continue consuming the worlds until the entire plane makes up its form, at which point, as reality itself dissolves, it will spill into the void. While this will not preserve the life itself, its essence will leak into other realities, greatly increasing the chance that a physical form of Mera will manifest in that reality, still discontent in a debt unpaid.
 * The Chiromata is killed. Once a Chiromata is killed, the missing value that it pursued is re-paid by the value added to those that overcame it. Those lives will generally have a greater feeling of peace with death, as their life is intrinsically bound to the essence of that plane. Once those lives die, the debt is finally re-paid and Mera will once again become at rest. Should any of those lives avoid death, they become prone to becoming Vile, as weight of their debt is far greater than that of an average life.

Prophecy
In the event that a Chiromata will spill into other realities, certain lives in that reality may begin to be persuaded by Mera, possibly even haunted by their image. This will act as a warning that these creatures will hold the chance to either stop or allow Mera to take form. This can affect anywhere from a singular creature to an entire civilization, and can take the form of anything.

Once a creature has interacted with Mera directly in this way, that life is guaranteed to be required to make that choice, however the method of choosing is still undecided, as is the time frame which this choice will have to be made in, including a choice that has already occurred. Time has no relevance to Mera.
