A young magician was sitting in his manor, very displeased with his raiding expedition for its failure. He had tried to make absolutely sure it could not fail no matter what, but none had returned and he definitely had no new knowledge for all his trouble, except that even if everybody tells you that a man is the greatest slayer to ever live, and you pay a massive amount of gold for his services, he can still fail. Prince Landen wanted what was at the bottom of that tomb very, very badly, and in his desperation he came to the conclusion to get what he wanted himself. He had great magical abilities and more than enough wealth to fund any expeditions down to the darkness below.

The royal guard, Shining Star, awoke with the others to the sound of an immense amount of magic being discharged. Having been trained for situations like this, he was up from the ground in seconds and wide awake, along with the rest of his troop. The royal guard scanned the surrounding area for the source of this power until he saw Princess Luna herself battling the demon he had been sent to compromise. Once Celestia had awoken and saw what was going on, she had dispelled the magical barrier surrounding the encampment, allowing the honorary soldier to sprint out towards the spot of the conflict. He lunged at the beast that was doing battle with his beloved ruler. Unfortunately for him it somehow saw him coming and spun around, stabbing him right where spine met skull, killing him instantly.

So these horses were mortal, his blade had proved. Why was the first one not killed by the direct impact with the tree, there was surely much more force in that then his arm's swing, Henric thought as he swung back to face the raging beast ahead of him. Seeing its horn charging for another blast, he ducked into the forest and started running. The creature was able to at the last minute convert the blast spell she was about to fire into a simple telekinesis spell. With all the power she had charged it was powerful beyond belief, Henric could not escape from this one.
The deep blue one spoke, "What do you have to say for yourself on the murder of a royal guard and the assault of Rainbow Dash?"
At these words Henric felt himself grow stronger. Red mist encircled him and flowed inside him. He could overpower this beast, and he knew it now. He replied with the speaking of an ancient hex from the time before his world was conquered by the great king, Alzarda, and demons of hate incarnate were the gods of all.
The very ground beneath Luna's feet became flame as a portal to the underworld made by Rishna himself opened and began tugging at her soul. This commotion understandably caused the princess to lose her concentration, releasing Henric, who watched as the goddess of the night was sucked directly into hell.

Celestia watched in complete horror as her sister was taken to an unknown dimension. There was no doubt that this was a wicked nasty demon now, but still she thought she could not outright destroy it. The beast probably was the only key to retrieving her sister, and after a thousand years without her, she knew losing her again would do herself in. In desperation, for now she knew the power of the creature and would not directly confront him, she decided reasoning with the strange demon would be a good way to go. Celestia was very wise and she knew that demons could be tricked by those with the cleverest of tongues.
"Please, Stop!" she cried, "We do not wish to do harm to you, guards stand down!"
The armor clad ponies preparing for a would have been thoroughly epic battle backed off leaving Henric free to speak, so he took advantage of this lack of hostility and replied, "Then why has all you have done while I was hear been trying to hurt me in some way?"
"We apologize for that," the sagacious alicorn replied, "But now with the promise of no further hostilities, would you please bring back my sister?"
"What sister?" Replied Henric confusedly, "Oh, you mean the blue one. No, once one has entered Rishna's lair you will have to physically bash your way through every decayed soul who has ever had their life taken from them, and hope you reach the one you want to save before they have been consumed. None have ever returned." And with that he teleported away about a hundred feet through into the forest and sprinted to his left, staying near the edge, but the horses did not know this.

The goddess of the night had just been sucked into another dimension. This was all she knew. Upon examining her surroundings she found she was in a barren, red landscape that seemed to be made completely of flame. There were far off moans coming from all around she thought she could see spirits forming in the wind every now and then. She began treading through the fire, noting it did not even feel warm, but instead icy. What was she to do? there was no food, water or sustainability in this wasteland, then she saw him.
Rishna was the demon lord of death in the world Henric was native to. He was made mostly of fear and a bit of anguish, so had no definite shape that he was restrained to. He was in fact the underworld itself and could manipulate any part of it as easily as a human could close his own hand, but for meetings like this he chose the form he had before ascending to godhood. He had been one of the three most powerful demons to walk the world, before his soul had been bound to the realm of his creation. This monster's was the form he had decided on before his planet had even been fully formed. He laughed as he approached Luna, but the sound was not emitted from the creature, but from the very walls they were contained in.
Rishna spoke, the world around saying, "It is not everyday a true goddess is sent to my humble realm, and bound with that mortal body too. Please, enjoy your stay."
The goddess of the night replied to the very incarnation of death by spitting out, "You foul demon of demons. Release me back to my own realm before I bring down the very heavens to split apart your putrid soul and release thy own demons to devour it!"
Rishna chuckled again. This new one was brash, angry, and did not seem wise as a god should be. Almost as if she had lost a thousand years of existence and had never had time to catch up to being a true god. Even so, he liked her. He knew he would release her when the time came, as a god of any sort could not be kept from their own land for long, but this did not mean he could not have a bit of fun first. With this death itself receded back into the realm it was, leaving behind Luna, alone, again.

Henric was tired of this monotonous game of cat and mouse he and the ponies were playing, as it was getting him nowhere fast. He decided the best thing to do would be to learn what he was dealing with. How many of them were there? What were the differences between this world and his own? How could he leave? He decided to look for a pony settlement he could start from, nothing to big. He would work his way up from here until at the lead government of these creatures. He would probably assassinate their rulers and take this world as his own, binding him with the magic around making the barriers between worlds easier to manipulate and aid in his return. Once back he would track down and kill that child who had sent him to do this, not for his own sake but to show to others that he was not to be fooled with.

The one who had sent Henric on his task was now entering the tomb of his magical idol. This Cornelius could feel from his crypt. He could manipulate the grounds above to kill the intruder just about instantly, but he did not. He had plans for lad on top of being a little fond of him, after all, he was his eighteen-generation great grandson. This connection of bloodlines would make it less energy consuming to see what he saw than with Henric. He would wait for the young man to come within a safe range for him to call out with his voice, and coax him through the portal. He could then instruct him on what to do from there on out, and channel his energy through him. He would gain power until he had enough to construct an immensely strong demon, which he would take control of and use as his new body. This was the plan.
