Deep in the field of parallel Universes, there lies one in which life itself can be made of light.
As this light takes many forms, it gains consciousness in tandem- much like our own idea of life, these figures, often faceless, nameless, are said to be The Precursors.
The Precursors are a genera of Angels, in which their origins are vastly unknown, though some individuals claim they are born from the nebulae that dot all galaxies within this parallel.
Here, we can see Precursors interacting with the nebulae in which they favor, most interested in stars of varying sizes.
And if you look deeper into the field of space... you may just find another being hidden in its veil.
