I think it's sth connected with the atral bodies like white dwarves,superNOVA stars...They existed as long as a time(world) and they are still creating/annihilating they selves...Dark they are from the power of they natural environment(space >lol<).It can be element(CHEM) of they structure which has green color(i sux in chem so dunno).One as a element of all stars and many as a countable ammount which 4ex. single star includes.
