Sutekh.

Unlike his present self, Bang-sul has a much deeper knowledge of his own mind. Being blind has actually helped him to achieve many things, it can safely be said that blindness also made it easier for him to master his powers, since it left him in a state of desperation that cannot be described.

Now, it happens that his previous Jewel was very connected to mind, unlike the current one. Just like the dream-sharing was a proof of this involvement.
In the years, through sleep, he also had access to those memories that were taken away from him, although he, at the moment, still believes those events he witnessed to be just dreams.

Living inside the Palace makes him a little cut-out from most of the events occurring outside. He keeps himself as far as possible from his present self and the Princes, thus there are many things he can't know, unless LianBi tells him.

It's night. He is still basically living in the Emperor's quarters and at the moment they are sleeping in his bed.
Bang-sul is a little restless though, he has a strange feeling that keeps him awake.
Suddenly, screams right outside the building get him to sit up. LianBi too wakes up immediately.
Guards shouting and threatening, maids screaming, some eerie growling noises...
"Stay here", says LiamBi, standing up from the bed.
My ass - thinks Bang-sul, who stands up right after the Emperor and follows him outside.
He can't see, but Jeonha suddenly pushes him behind himself, as if to shield him. He must really think he is as weak as he behaves with him. Tsk.

"GongPo." Another one, wee, the heaven for Seth.
To that, it's him to push LianBi behind himself. He can't see what the other looks like, but the voice too is that of the eunuch and he knows for sure that boy died. It wasn't the kind of death that leaves doubts, he was decapitated, entirely. First thought: zombie apocalypse? Damn, JJ was right...
"What have they done to you...?" says Seth, probably referring to his blindness.
"Why are you here? What do you want?" he decides to act as if he knows, although he didn't get who the other really is.
"It is what everyone keeps asking me. You know who am I, don't you? You remember."
"You can't be who I think you are." Also since if he was that eunuch, he should be bones by now.
"You know me by the name of Seth."
Bang-sul gets like petrified. All the 'dreams' he had suddenly appear in his mind again. Dreams be actually enjoyed and gave him relief in some.lf the worst momentd of his life, after the death of Qing, where everything else seemed nothing but sorrow.
The question that would come to his mind is 'you are real'? But he somewhat doesn't want to give away too much, in front of LianBi and the others.
"I have a gift for you. The other you is not ready yet."
What the f*** should that mean? Ready for what?! - he thinks. He feels something close to him, not a person, just an object hovering in front of him. With some hesitation, he raises his hands to take the item. It's obviously a sword in its scabbard... and he recognizes it at the very first touch. His katana, the one Haru sold on Earth, that he thought the police had stolen.
"The sword your grandfather sent you, from Japan. You liked it so much."
F***, f***, f***... it was all true, it was all real - he thinks.
Loud, disembodiment growls. A man screaming in tremendous pain, more screams and general panic. Bang-sul tries to keep calm, but the fact he can't see nor guess what's going on is giving him a hard time.
"Stupid children of Dolash!" hisses Seth. "I will be back." His favourite line so far.

Double f***. Now he is left alone with a bunch of semi-hostile people thinking he is friend with that crazy dude.
"Jeonha... this demands emergency status and immediate interrogation", says a manly voice.
"Strengthen the defences on the Western Quarters, keep the Princes safe", replies LianBi in a clearly shaken tone.
"What about Concubine Yi, Jeonha?"
"Summon Yang and JunYin, tell them it's my order, they have to come..." Someone is seriously upset.
Bang-sul is not sure he wants to know what happened to scare LianBi so bad, but it must not have been a pleasant sight. One first good thing about being blind?
He gets grabbed and pushed against the wall, quite roughly. "Who was that?" asks the Emperor, in a mix of anger and worry.
He takes a few deep breath, hesitating a little to speak. Plus... well, when LianBi acts angry he gets totally petrified, especially when so close. "S-someone i... think I knew..." he says in a trembling tone.
LianBi takes the katana from his hands. "Why did it give this to you? How does he know you? Whose is this blood it's covering the whole sword?!"
Bang-sul covers his face with hands and starts to cry. Future Tero is such a crybaby while present one would rather tear off his eyes than let anyone see a single drop coming out of them. He is a little overwhelmed though. "Please..."
"WHAT? THAT MAN MANAGED IGNORE ALL OF THE DEFENCES! DO YOU EVEN UNDERSTAND HOW SERIOUS THIS IS?!"
He jumps and sobs at his shouts. When a strategic doesn't work it doesn't work.
LianBi hits the wall with his hand, very close to the other's head. "You must tell me", he hisses.
"I need a moment", he sobs. "Just a moment..." Although those memories are 'unlocked' they are a total mess, spread among different dreams and a total chaos of unconnected events flashing in his mind like a storm.
"YOU MUST TELL ME NOW!"
"I NEED A MOMENT TO SORT MY MEMORIES!" he shouts, but in a desperate tone, rather than angrily. Then sobs again. "It's not so easy..."
