Jumna

Not sure of their existence but can't be denied either, a form of energy lifeform. Some call them “Ghosts” or “Spirits”. This is the only image we have of them and it's not sure it is the true form.
Not much is known about them, at the exception that they gather information, for what purpose, it's not known either. They also seem to have an enemy, it would seem that they are the same species but have a difference of opinion, those call themselves the Pjin.
The Pjin seem to be trouble makers, then the Jumna, but that is still to be determined.
