LOTM: Witnesses of Sleepy Hollow/Characters/Hidden One's Army

The Hidden One's Army, composed in four parts - the Hidden One's Servants, Agents of Pandora, Agents of Leeds and the Black Host - are servants and demons serving as the cultists worshipping the evil Sumerian God, Etu Ilu, better known as the Hidden One.

The Hidden One along with the other gods created a box to contain all of the evils in the world after they banished them. After, the Hidden One was tasked with looking after the box in the Catacombs. Every day, a human would grace his presence and offer him a goblet full of human blood to symbolize their submission. One day, the servant, Pandora, delivered him the goblet of blood and offered him a flower.

The Hidden One, surprised that she would put herself at risk giving him a flower as it is forbidden. He asks why she would give him a flower. She tells him that she only wanted to bring him a bit of joy. He kisses her hand softly. He asks her why he remains in the dark while the other gods remain in the light. She shook her head. The Hidden One tells her the early history of the gods. He also states that the only way to kill the other gods is to use the evils in the box. Once the Hidden One bestowed Pandora with great power, she gathered her brethren and unleashed the evils of the box onto the gods, killing them. Once it was all over, the Hidden One and Pandora were together, for a brief second. Humanity banished the Hidden One for all of eternity to the catacombs. After the Hidden One was banished, Pandora made it her life's goal to recover him from the catacombs, taking it upon herself to look after the box.

Thousands of years later, Pandora used the Witnesses need to save lives from Moloch and the Four Horsemen of the Apocalypse as a method to open the Tree of Fear, creating a passage way to Catacombs in order to free him from his prison. Then, the Hidden One and his servants replaces Moloch and his servants as the major threats of the Witnesses after Pandora sealed the Four Horsemen into the Catatombs.

Hidden One
"By sundown tomorrow, I will be the one true God, and I will wipe away this world, you included! Then you will see just how far my reach extends. You love these humans so much....You wear their clothes.... You feel their petty, worthless emotions.... If you want to live among them... then you shall die among them!"

Etu Ilu, which roughly translates to the Hidden One, Hidden One is the main antagonist of Pandora Saga (as well as the original series' third season). He was the major part of the Second Tribulation and the person that Jenny Mills saw when the Shard of Anubis was absorbed into her skin. He came to her in her dream and her skin started glowing red orange and her eyes turned white. He appeared as a dark-skinned, bald man in a hood. It was discovered by Ichabod, Abbie, and Joe that he was an Ancient Sumerian god. He appeared to be romantically involved with Pandora, whom he gave a special box said to contain all the evil in the world.

It is uncertain how much he truly cares for Pandora. While he shows affection and concern for her sometimes, at other times, he expresses digust at the notion of love and human emotions, viewing them as weaknesses. Pandora is clearly intimidated by him and knows that, even when weakened (and slowly returning to full power), he is more powerful than she is. The Hidden One aims to rule the Earth and it is implied that he may have attempted to do so in the past. In the end, he turned on his wife and freed the greatest evil, which he than adsorbed in to him self giving him god like power and he planned to destroy the entire world.
