Demons Of The League Of Assassins (A PJO and ARROW CROSSOVER)

Chapter 4 - IV: Undying Warrior

1 Flashback 05: Does dying still mean something? Or Hard to die, Harder to kill

Nanda Parbat

Ra's' hand fell to his side. They were all frozen, staring at the sword in Percy's chest. The silence was only broken when Percy pulled the sword out of his chest. The blade was as clean as it was before. He looked stoic at the sword in his hands, then up.
"That didn't even tickle, but it's irksome you had to ruin my shirt."
Said shirt had two holes in it, one on the backside one in the front through which the unmarred skin could be seen. Percy drove the sword into the stone floor, not taking in the astonishment of the two other people in the room. One was astonished, because his opponent was not even bothered by the sword that, moments earlier, had been in his heart, the other one because of the already mentioned and the fact Ra's al Ghul was back from the dead.
"Sharp Blade, not every sword can cut through stone", Percy complimented. He turned to the other two and set to speak on. However, he never got to utter a single additional word. The fight had ultimately taken its toll on him and he fainted toppling over backwards right into the pool behind him.

2 Speed up Healing

Nanda Parbat

Al 'iiesar sensed the water coming to him and directed it to Malcolm Merlyn. He spread a thin layer water over all of Malcolm's injuries and tried to will them to heal. And really slowly but surely the most severe of the wounds and broken bones started to mend as the water seeped into them and changed something. Though it also happened something that Al 'iiesar could not have foreseen. Al Sa-her's arm stump grew a bit and new bones where forming. Al 'iiesar's reserves were depleting so fast he had to stop, as soon as he sensed this change. No sooner he stopped than he nearly fainted. As promised the priestess was on scene and poured out a barrel of water over him.
"What the hell was that?", he croaked barely out laying with his back on the floor and his eyes closed.
The ever so stoic priestess was the one who answered him, "You obviously healed a part of his severed hand which put such a great strain on you. You almost fainted."
He opened one of his eyes, hardly visible, due to his sunglasses, "That was a rhetorical question."
"And that was a statement."
He just rolled his eyes at her answer and tried to get up.
"So now tell, professional, is he better?"
The priestess took a look and answered, "Yes, it shouldn't be long until he wakes up, merely some days instead of weeks or maybe months like before. You, on the other hand, should sleep. Ra's requests you to present a training exercise."
"Right, I nearly forgot that. Thanks. And please notify me if he wakes up."
"I will, Al 'iiesar."

3 Tardy By Mistake

Starling City

Oliver Queen was late, again. Only this time he was not late for a meeting or too late in stopping a crime, no, he was late for a family dinner. He had promised William to be there on time. Although there was always something almost as if the odds were stacked against him. He did not want to disappoint his son, but despite his best intentions, it happened.
The previous night he had spent more or less sleepless trying to think of a way to introduce Felicity to William as his girlfriend without William resenting Felicity. Consequently, he was dead tired in the office and after reading the first few pages of the paper he was given to read and partly sign, he fell asleep on his desk. Luckily Quentin Lance noticed the sleeping mayor, woke him up and send him home. Still, after his wake up it was already late, too late for his dinner. So he hurried as much as he could and tried his best, but he could already feel his son's disappointment.

4 Flashback 06: Percy's Dream

Percy's Mind

He was in Tartarus, not that it was something new. It was his third time down there now, but it still kept some of its horrors. He stood behind the House of Night at the edge of a cliff after encountering the terrors of the Mansion. Terrors, so horrible it was well-nigh impossible to even give describing them a try. Percy was forced to his knees by two hellhounds commanded by the women in front of him. Nyx towered tall above him in her godly height.
"If I could I would have killed you a long time ago, godling. Though as it is my daughters allowed me to test you. You seek security in those shackles I intended to bind your powers with, so all creatures in Tartarus could torture you. And although you broke free, now, after years you are back here."
Percy felt dread at these words, he never really liked tests and he did everything he could to oppress the memories of his second stay in this hell hole.
"And despite all the things these shackles mean, you let them on because you are too afraid of your own powers. How pathetic", Nyx sneered, "I can't kill you and with your domains, it's nearly impossible to make you fade. Except there is one way to destroy you, of course, there's a slim possibility you could survive it. That's your test."
Nyx shrank to normal human height, grabbed Percy by the collar and yanked him closer to the edge, then she put him back down. He could feel what was behind him and it terrified him. Terrified him so much he could not even speak.
"You know my daughters, the Moirai, send their greetings, Perseus. Try to survive this trial because I want to butcher you myself. But even if you won't make it, at least I get the satisfaction of being the one, who lead you to your ultimate demise. Enjoy the Abyss of Chaos, Perseus Jackson."
With that said she trusted him into the abyss and he was falling, falling down into black nothingness.

AN: Next chapter is already in writing. Hopefully, it won't take that long to write, but I promise there will be a long and badass fighting scene.
