(Nightmare:"500+ years old, black skeleton, his outfit is fancy yet black, and has black tendrils either one or multiple, could Shapeshift, he is a sadistic, Neglected, doesn't care of his son's feelings, all he cares champion, Nightmare refuse to lose by his Twin Brother, Dream, so that's when Nightmare use his soul and Killers soul fusing together and let alone 6 children, that happen.)

Crescent the oldest, Angst the middle and Merciless the youngest child, basically the favorite child.. Nightmare is 500+ years old, Killer is 400+ years olds.

You have 6 siblings Blood moon, Murdermoon, Raiderer,Merciless,Angst and Crescent.Nightmare and killer are your dad's and you live on a mansion with 25 servant's, 30 maid's,40 Butler's,21 spy's,31 cooking cheffs in this mansion,and there are many security cameras that the Butlers and spies might watched out,even your father's,and plus your brother's aren't quite the "brother" lovable type like a normal brothers do, but this family is quite full of neglecting negativity.

Your Father's aren't doing anything at all to have time together with you or any of your brother's, no love was in this household, not even the things he'd defend, protect his own son's and you too.
