Backstory: Born long before any of the gods, titan dragons/beasts, Primordials or the mortal races, he was the king of a race of beings known as Shadows. They were powerful beyond imagination, capable of taking over entire dimensions within minutes. They had a powerful enemy, beings known as Lights, who matched them in every way possible. One day during his life, Hollow fell in love with a female of the Lights known as Cassandra. Trusting her completely, he led her to the capital of the Shadows, which had been hidden from the Lights for countless millennia. Some time after that, he returned from a visit to her home to find the capital in ruins and all of his people slaughtered. Stumbling across a dying Shadow warrior, he found out that the woman he loved had told her people where the capital was, betraying him without a thought. Consumed with guilt and despair at this news, he gave himself completely to the darkness that all Shadows were born from. Emerging as an immortal, he used his newfound powers to eradicate the Lights, and when he came upon the woman he held so dear to him, she fell upon her knees and begged him for mercy. He simply helped her up and pulled her into a hug, kissing her gently before whispering into her ear. "I have no mercy for those who betrayed me." Then he drove a blade through her heart, laying her gently on the ground before walking away, a single tear going down his face. Now, he wanders the multiverses, his actions and the memory of his past having drove him insane as he looks for anything that will entertain and amuse him. (Hardly anyone knows of his past, but those who do know it keep it a secret at his request, as his past is quite painful for him to remember and think about)
Backstory Note: There was a Light who actually protested against the slaughter of Hollow's people, who was Cassandra's best friend named Athena. She was exiled to an unknown realm due to her protests, as she is now the last Light left alive. Hollow had recently heard of this from CrowMessenger, and has servants searching the realms for her location. (Got this idea from DeathR1pper)

Quotes
"You cannot harm me, child. Now put the weapon down, before I make you."
"So tell me, little one, how would you like to make a deal with me?"
"It has been a long time, Blackdread. How have you been after all these years?"
"You ask me why I am here? Well, I was bored, and had nothing else to do. Besides, so many interesting individuals gathered on one island can make any being curious."
"I will gladly help you, as long as you have something I could want."
"This just keeps getting more and more interesting."
"Come then, child. Face me, and then you will see why even Blackdread himself respects me." 
"I can count on one hand the number of beings that have the power to face me, let alone beat me. Do you think you will become one of them?"
"You are just another lost soul, destined to become mine."
"So many beings. Gods, half-devils, hosts, dragons, humans, synths, and many more. A fight with all of you would be entertaining."
"The shadows betray you, because they serve me."
"You mortals are so amusing, with your fragile little bodies and weak hearts. You make my existence worthwhile, and entertaining."
"Death is no obstacle for me. I have the capability of bringing anything and anyone back to life, for reality itself bends to my will. But, what are you willing to pay in order to change fate?"
"I will not allow you to harm Nihil's lovers, or his children. They are under my protection. So please, attack them at your own peril."
"I am not a god, they are lesser beings compared to me. No, I am something better........much, much better......."
"I will restore my kingdom to it's former glory, and find a way to bring my people back from the dead, at all costs."
"If any of you dares to speak ill of my Athena, or put their hands on her, I will personally send you back to the Void. Do you understand?"
"I do not have a single shred of sympathy for you, and I have no use for apologies."
"The death of the second Nihil has set my plans back, and that annoys me. It will take months for me to accommodate for this, and that will cost me billions of souls in the process."
"The end of your worlds is coming..........and I, will be the herald of the new age. The age, of the Shadows."
"Fate has no hold over me! And I will make sure it never holds sway ever again!"
"Before light, there was darkness. And there shall be darkness once more when everything dies. That is why I cannot die, for I am darkness itself!"
Notes
-He loves to make deals, as most of the time they bring him entertainment. And once he makes a deal, he will honor it, unlike most immortals.
-He hates Shad for being the so called "Shadow Lord", believing that he is nothing more than a insect and a weakling, though he has shown to have an interest in his daughter, but the reason for this is entirely unknown to all except him.
-He is capable of fighting off Primordials with ease, and can face a Titan dragon/beast on equal grounds.
-He respects Titan dragons/beasts because of their strength.
-The amount of pressure that Hollow lets off can make even a Titan dragon/beast tense, and anyone weaker than a Titan dragon/beast ends up on their knees from it.
-He only gets involved in things that greatly interest him, other than that he observes and interferes when he feels like it.
-He has his own sense of honor, and will not attack anyone who does not have a weapon, does not attack him or does not show hostility to him. He will also not attack women or children unless forced to. 
-He can devour ghosts and the souls of the dead, adding their power and knowledge to his.
-He can be called for by looking into a shadow and simply saying, "Hollow, I wish to speak with you". And he will appear out of the shadow as though he was walking through a doorway.
-He knows of the multiverses, and has spoken to many people from the different dimensions.
-He has no soul, considering he technically does not even exist.
-He knows CrowMessenger and Forsaken One fairly well, as they also know of him.
-He lets off a aura of emptiness, despair, and coldness, which can affect anyone who feels it. He can also switch it off and on at will.
-He knows everything about Ru'uan, and everyone in it.
-He has a habit of spinning and flipping knives in his left hand.
-He has a habit of smoking that he picked up from living among humans on Earth.
-He has a distinct hatred for the Primordial of Light, Uriel, as she is one of the only beings capable of actually hurting him. She also reminds him of his ex, Cassandra.
-He had a hand in causing the Great War in Remnant, and many wars on Earth, including but not limited to WW1, WW2, Civil War, and the Revolutionary War. He has even influenced every war that Ru'uan and Sparta have been in, and are currently in, going to great lengths to make sure no one knows of his involvement.
-He has a complete immunity to dragon steel and it's venom, while possessing adequate knowledge in how it came to be, making many wonder exactly who and what he is, and why he has shown up so suddenly.
-In his true form, Hollow can easily manipulate the universes to his will, as can his wife.
-He is always a gentleman to women, and will help them if they need it.
-He has fought several pantheons of gods over the years, but mostly the Greek, Norse, Egyptian and Roman gods/goddesses, letting them live each time just to stave away boredom.
-Hollow actually had a hand in many of Nihil's atrocities, such as the slaughter of the Steelclaw tribe, convincing Nihil to do all of this with dreams and whispers, while collecting their souls.
-Hollow has been known to bring the dead back to life, just to mess with Blackdread.
-Hollow created all the different versions of Nihil, no one not even the titan dragons/beasts know why though.
-The Nihil he created has Hollow's symbol branded on the back of his left hand, as does his family.
Very Important Note: DO NOT trust Hollow, under any circumstances. The only time he ever helps anyone is when he knows he will get something in return, and only appears when he knows everything will go his way.
Secret: He is actually Nihil's patron, and the protector of his family, seeing Nihil as the only being worth helping without getting anything in return, as he and Nihil are the only Shadows left. (He actually recreated Nihil with a combination of Shadow and demon DNA, which is why Nihil is so efficient when it comes to using shadows, only Hollow knows this)
Secret 2: He actually considers Nihil to be like a little brother to him, though he will never tell anyone that.
Secret 3: He was in love and still is in love with Athena, Cassandra's best friend.

Symbols(Instead of blood red, it is a dark purple)(Nihil's family and Nihil himself actually bare his symbol, to show they are under his protection)

(This is his former symbol, when he was still king.)
