The Federation of Blood and Hearts, or 'Blood Federation' for short, was the name of the coalition that served the Venerable Blood Tree.
29 years ago (Year 149), the Beast of Envy appeared and began his unstoppable conquest. Sinbad had only been 16 at the time and news of what had been happening had been terrifying. The world as he knew it had undergone a huge upheaval and there was nothing he could do about it.
Before then, although he had spent most of his time worrying about how he could avoid Ghost and secretly raise his strength, his life had been relatively peaceful. His 2 parents, Sindia and Balik, were respectively a Fiend Lord and Demon King. The duo were at the top of the food chain and most people avoided provoking them. Sinbad being their son enjoyed a great deal of protection.
Ghost may have banned him from raising his cultivation but he was still able to entertain himself in more mundane ways. Life was dull, but it had been stable.
With the arrival of Envy, all of that had changed. There was no longer any guarantee that he could live to see tomorrow - and being the young boy that he was, his rising anxiety had led to him momentarily losing control of his Mana.
This wouldn't have been a problem if he were a Blood Fiend or Monster, but he was a Devil and such people weren't supposed to have Mana in the first place.
Regular Devils didn't have Mana Circuits or a Mana Core so how could they have Mana? They may have a strange strengthening system that improved their bodies the more blood they absorbed (similar but different to Anatomy Refinement), but they could not use Magic.
Sinbad was different from them. He had Mana Circuits and something even greater than a Demon Nucleus so he could absorb ambient Magical Energy any way he wanted. This was not something Ghost knew about and was not something that he ever had intentions of letting the Progenitor know about if he could help it, so moments like that where he lost control of his Mana were very worrying for him and his parents.
To be honest, the amount of Mana he had wielded had been so low that he hadn't even entered the 1st Stage of Cultivation. Such a thing was very hard to detect even when he flared up, but caution was a thousand times better than regret, especially when Ghost was involved.
Sinbad was able to regain control of his Mana on his own, but to make sure that he fully calmed down and didn't have another accident, his parents finally revealed to him a plan that they had been harbouring for years. Their plan to escape.
As was obvious, Sinbad was no longer in the Blood Fiend territory. Their plan to escape had received resounding success.
Sinbad's parents had audaciously recruited Devils from both the Blood Fiend and Monster territories in secret.
Sinbad was very aware of the fact that that left on their own, the Devil race had very cruel and insidious personalities that were very deserving of the torment they received on a daily basis. However, they were not foolish. Far from it. They were quite intelligent and that was even without receiving teaching.
There was not a problem in recruiting such people if you wanted to collectively escape for a better future. The chances of betrayal still wouldn't be zero of course but Sinbad's parents took care of all the loose ends they could. The problem only came after you reached the destination. How do you take care of people who will want to kill you and each other? You don't.
2 years after Envy's arrival (Year 151), Sinbad's family and the Devils had taken advantage of the storm caused by Envy to launch a vicious attack on both factions, following this they quickly escaped towards their already established goal: The Forest of Bloody Origin.
According to his mother, this was the forest that the Blood Fiends had originated from, but unknowingly, something menacing had appeared in the Forest that changed its landscape into the crimson horror that it was today. The so-called 'Demonic Blood Tree'. An expedition led by Ghost had almost resulted in a complete tragedy when they arrived here, and it was this dangerous place that his parents had led him and the Devils to for safety.
It soon turned out that Sinbad's parents were intending to exterminate the Devils to offer them as sacrifices for the Tree that they were sure was intelligent. From the beginning, they had never planned on taking care of the heartless creatures known as the Devils.
However, Sinbad had different ideas. The reason why he wasn't as vicious as other Devils was because of a Physique he possessed that had been inherited from his father, with some differences. His father's physique was called the Divine Demon Physique. It was something that all True Demon Kings had and was the reason that Monsters were able to establish a civilisation.
His father had already shared with him the effects of his Physique and it went as followed:
1) Divine IQ: Above mortal intelligence from birth.
2) Divine Monster: Killing Essence you absorb will be automatically purified.
3) Divine Presence: Everyone facing you will feel like you were an existence that came from above. Monsters will especially revere you and enemies will instinctively fear you, causing them to be unable to fight against you with their full power if they lack will power.
4) Divine Ruler: Everyone that follows you will be influenced by your thoughts and decisions. If you want to be a good ruler you will have good subordinates, if you want to be an evil ruler you will have evil subordinates.
5) Divine Demon: The stronger you are the more attractive you become. You will also obtain 2 curved horns on the sides of your head that are very attractive and at the same time very imposing to other Monsters. They are also great Mana Conduits.
The horns will always be on the side of your head and will always curl upwards but the design of those horns will match your personality. As a result, if you experience any grand changes in personality, so will your horns.
You will also obtain personalised Killing Essence/Demonic Energy, no longer will your Killing Essence/Demonic Energy be red in colour like other Monsters unless red is a colour that represents you.
6) Divine Damnation: Shoot a condensed beam of Pure Killing Essence/Demonic Energy.

Apparently there was a 7th effect, but his father had always told him that he wasn't ready to hear about it yet. Somehow.
In any case, the Divine Demon Physique was very powerful. But what had occupied his thoughts was the Divine Ruler effect. It was because of this that the True Demon Kings were able to establish nations that had rules and order.
This was a deep secret that only a few people knew about, so when the True Demon Kings later fled or died in the war against Envy, everyone had been confused by why the new self-proclaimed Demon Kings were unable to control others in the same way. New ones kept rising and falling every month and only a few were powerful enough to forcefully hold their positions, but it was unlike the control that a True Demon King could hold.
Why was this important to Sinbad? It was because it was this same impressive 'Divine Ruler effect' that Sinbad had inherited in his own physique. His father's Divine Ruler Effect only worked on other Monsters, but what about Sinbad's?
