What brings you here,said The Sorcerer. The Author he changed things. He changed Laurel Lance's fate; he'd made her die in the hospital. There must be a way to undo it, said The Apprentice. I'm afraid not. What's done is done, my apprentice, said The Sorcerer. What now of Oliver Queen, what of his fate? said the Apprentice. Remain entwined with Nyssa al ghul as they always were and always shall be. Our concern now is the Author, said The Sorcerer. I have taken care of that, master, our mistake has been rectified. He is in the book, where he can no longer alter our world, only record what happens, said the Apprentice. You must see to it there no more damage. The Author must never be allowed to toy with fate again.
As The Apprentice observe from afar, he sees Oliver Queen and Nyssa al Ghul getting know each other better, they started to date. They became very close. Closer than ever. Then they started working with each other and they killed Damian Darhk together. Then they both learned that they were meant to be together, then they consummated their relationship and weeks later they found out they were going to have a child and their child would be loved with all their hearts. As they were walking, they bump into the Apprentice and they didn't know that he has been watching over them from afar. They were being followed by someone who wanted to tear them apart that was no other than Oliver's mysterious cousin who was once Rumplestiltskin's apprentice in the arts of Dark Magic. He is the Lord of Darkness and he is preparing for the arrival of his master, he is the source of all darkness and evil. He is Trigon and soon he will arrive on earth and conquer it.
In the lair of the Lord of Darkness
Master, they don't suspect a thing, soon you will be free to conquer the Earth, said the Mysterious cousin
