Refraction

Refractions are a phenomenon that happens in Aralla, known cases mostly on the continent of Ekrune. Refractions are caused by the The Cradle and its latent energy interacting with powerful souls. When The Seven were diffused into the cradle, their powerful souls were too much to absorb at once, and they were split and refracted into many smaller unique energies (the players of aralla represent these energies). These unique energies inhabit those blessed by the Seven (characters played by players) and gift them with control over their own fate and destiny. The observed phenomenon describes Refraction as a soul of the "player" inhabiting different characters, with different memories, yet they were all connected as they share the same soul, the "player". There are unique limitations and aid that the Refraction can share.

They share one main soul, and so, if one dies through the means of a Greater Scarlet Death, all other Refractions will die in the same method.
During the time of need, a refraction can appear in the stead of another, or can aid a fellow refraction in battle.
In special cases, refractions might share memories from other refractions of theirs.
