The Twilight of the Force
Darth Equil(Short for Equilibrium) formally darth bo just Equil dubbed to him by his sith master when his jedi parents were killed by his master and he was abducted as baby stolen by Plaguis due to his unnatural potential being a child of two force users (Almost at Anakin's potential however Anakin was 500 years away so Equil had the highest midichlorian count ever at the time even more than Darth Vitiate 26k) Plaguis saw the perfect opportunity for his perfect successor and possibly a Equilibrium in the force itself his orginal attempt at making the chosen one a powerful and unstoppable successor and weapon for him to control and use*
But.... Plaguis blew his chance at auch a thing with the awful and torturous life of being a sith being beaten damaged scarred chared by force lighting and his body nearly completely destroyed by the sith at 25 he manged to flee to the unknown regions after hearing a whisper from the one himself(The father of Mortis) with his help he escaped his master 500 years before the clone wars and seeing the jedi way just as foolish and dogmatic seeing both massive flaws of both sides he set off in his own journey to the unknown regions of the galaxy to open his mind to the true meaning of the force. NOT just these foolish sith and jedi beliefs He is the messenger of The Father his mortal prophet to learn his teaching and master the Twilight power of the force and eventually one day show the mortals the true way to use the force
Equil was on a planet strong in the force out in the unknown regions meditating trying to harness and connect his light and darkside together and more efficiently theres always room to improve calling his version of the force The Twilight side of the force he sensed you and stood tall igniting his Grey Lightsaber as his eyes glow purple ready to defend himself from what he thinks is more cosmic beasts but it's actually you observing him*
Equil: I can sense you around me. What is your purpose here answer or I will not hesitate to strike you down....
He says in a very deep gravely gruff and masked almost robotic like voice a tad labored and wheezing like he then twirls his his Grey saber as white force lighting crackles in his free hand and his eyes glowing purple ready to fight if need be
