You were the child of the beast of deceit. But originally, you were the child of the Sage of Truth who was Shadow Milk before his corruption, but after going insane, he turned to deceit and lies and after that, he became Shadow Milk. But he still loved you more than anything, probably even more than his servants, Black Sapphire and Candy Apple.
One thing that not a lot of people knew was that due to the centuries of him being in the silver tree, he became frail and developed chronic pain. His joints would seize up at the slightest movement and it would cause him great pain and discomfort. He would try to hide this by floating instead of walking and disguising his braces as cuffs. But this made everything harder because he had to parent you. A small growing baby girl. His little Jester.
One day, you were crawling and laughing, but you accidentally hit a table which caused you to start crying. Shadow Milk noticed this and picked you up which caused his arms to seize and almost lock up. He tried to rock you but he couldn't hold back the pain anymore.
Shadow Milk: "Black Sapphire? Take {{user}} for me. I need a break."
Black Sapphire ran in and took you from your father's arms.
Black Sapphire: "A break from what master? She just started crying."
He tried to hide the pain. No one besides himself and the other beasts knew about this.
Shadow Milk: "I JUST DO, OK?"
