Epic of Vampire Dragon: Reborn As A Vampire Dragon With a System

-----

A library! Usually, most people would think of it as a boring place…

​​

But for Chaos, it was an interesting place where he could eat sealed demons and magic grimoires to get more power, so he was eager to get there.

Belphegor had also mentioned that there was a surprise for him in the library, some kind of special artifact whose functions would make Chaos very happy.

"What surprise?" asked Chaos, he was stiff and expressionless but became excited over the surprise.

"Lord Chaos, it wouldn't be a surprise if I tell you before you see it, right?" asked Belphegor.

"Oh… I guess you're right," said Chaos while nodding.

Chaos walked through the large, almost endless corridors of the enormous castle that once belonged to his father, as Belphegor quickly guided him into the library.

After walking downstairs for a few minutes, they finally reached a large, red-colored gate.

"This is the gate that leads to the library. You see, my lord, only those authorized by Master Ainz can enter this place, and as I was his closest servant, I could easily-"

Before Belphegor was to finish his words, Chaos pushed the gate forward as it suddenly opened to his touch.

CRASH!

Albeit a second after, it cracked into pieces, thankfully, the pieces didn't fly inside the library.

"Eh? I just pushed it," said Chaos.

"GAH! T-The gate! M-My lord, you should be more prudent with your strength!" said Belphegor.

"Sorry…" sighed Chaos, as Belphegor wasn't able to get angry with his young lord.

"W-Well, we will make sure to train so you can learn how to use your power better, cheer up, my lord! We are here!" said Belphegor, flying inside the library as small, blue-colored flames, Will-o-wisps began to float around, lightning everything with their dim blue light.

Chaos eyes were able to easily see in the dark anyway, but he thanked the little Will-o-wisps for wanting to make things visible for him even without knowing he had Dark Vision.

Chaos slowly entered the large room, which extended over 30 meters, the ceiling was high above, and Chaos noticed a few paintings resembling a starry night and a gleaming white moon.

"Who painted that?" asked Chaos, as he found it pretty.

"Oh! That was painted by Master Ainz's long-lost wife, Lesithea… She was a ghost that loved to paint. Sadly, she died once when Master Ainz was gathering materials for you… She was caught by the enemy and Master Ainz was not able to rescue her because she threw him away with her magic, as she desired for him to keep existing… Before becoming a ghost she and Master Ainz were researchers of magic and alchemy… It is a long story… Your bones are made of not only Master Ainz's but also of Lady Lesithea," said Belphegor.

"I see…" said Chaos, understanding that such a beautiful painting held a different meaning. It was made by his mother.

He didn't know what to think, but his heart was bubbling with many emotions, he had never met her, yet he felt grief and sorrow deep inside.

And he also felt a lot of gratitude and the feeling that he owed her a lot. After all, it was thanks to her efforts that he was nowhere, born anew and with such amount of power.

He needed to make sure to live for his mother, and for his father too.

Belphegor glanced at Chaos, he was expressionless and seemed as if he were a corpse, but deep inside his gleaming crimson-red eyes, the blazing skull was able to notice some sorrow and grief emerge.

Quickly desiring to cheer up his lord, Belphegor decided to introduce him to the books.

"My lord, I am sure that Lady Lesithea would be happy as long as you can live a fulfilling life, it was the only thing she desired. After all, she and Master Ainz wanted to have a child despite being Undead whose physical bodies were mere bones, and in her case, she was a ghost. Due to that, they embarked on a journey to build a strong son, and you're the result of their efforts and dreams. Please, cheer up, my lord, I am sure that wherever they are, they will be happy as long as you keep striving forward and live your life to the fullest," said Belphegor.

Chaos glanced back at Belphegor as he smiled a bit... This was in fact the first time he smiled.

"Hm, you're right, Belphegor," he said.

Feeling happy that his lord has been cheered up a bit, Belphegor began to fly around the tall bookshelves.

"As you can see, my lord, there are hundreds of books in here, from Alchemy, Mathematics, Magic Understanding, Cooking, and many books written by Master Ainz and Lady Lesithea about their research on Alchemy, Undead, and Chimeras, which led to their final and greatest creation, you," said Belphegor.

"But I suppose you don't have much time to read all of such things yet. However, for now, I desire for you to devour certain enemies of my lords which they had managed to defeat and seal inside Grimoires… These were mostly demons that had pursued them their entire lives… I am sure that no one will miss them!" said Belphegor, as he guided Chaos into the second floor of the library, where four grimoires were releasing a dim aura and presence… that of demonic and malicious nature.

The fur grimoires were above altars, and they were being held tight by powerful seals made by Ainz, Chaos could clearly feel the power of his father still present within them.

The altars were all lined up, and before them, there was another painting from Lady Lesithea.

Chaos glanced at it, it seemed to be a painting of these four demons.

"What are the origins of these demons?" wondered Chaos.

"Hm… to resume everything, they were entities unleashed into this world by… your very parents. To acquire the power they possessed, they had first done pacts with demons from the Gates of Hell, an interdimensional Plane that Warlocks often make contracts with demons there… Master Ainz and Lady Lesithea had delved deep into the arts of warlocks and had done pacts with these demons. However, ultimately, these demons never had good intentions with them, and used them to come into this plane, tormenting them without stopping… They ruined their lives, but the two kept striving forward with their willpower, and managed to seal them one by one at long last… It is a story of tragedy and perseverance," said Belphegor.

Chaos began to wonder what kind of crazy life his parents had… to think that they did a pact with Demons from another plane to acquire power, but ultimately made these demons come in here just for these entities to torment their lives…

"Well, it is not like they stopped making pacts with beings after these incidents, but they had decided to never make a pact with Demons. Unlike Outer Gods, Demons are too treacherous. But Outer Gods are more direct with what they want… And thanks to them and their pact with Master Ainz it was possible for that barrier to be erected, which protected you all these years," said Belphegor.

"I see… Then let me a feast in these demons who had tormented my parent's lives. I am sure that they will be happy to see them be devoured," said Chaos.

"Oho! I am sure they will be!" laughed Belphegor, as Chaos approached his hands to the grimoires…
