A Railgun In Fairy Tail, The Soul Slayer Chronicles: Book 5, Sisters

Welcome To Las Noches.

Mikoto walked along the sands of Hueco Mundo.. everywhere around her.. she could see nothing but the endless silver desert that glinted in the light of the moon that sat above the land of eternal night...

In a way, Mikoto figured Hueco Mundo actually had a dark beauty to it.. the sand was so smooth, white, and silver... the world was so silent.. so quiet...one could settle down here in the soft sands and just sleep. Well if it weren't for Runuganga that is..

There was just one structure that could be seen in Hueco Mundo.. and that was the massive palace of Las Noches..

She could hear a voice calling her.. beckoning her towards the massive palace. A beautiful beckoning voice that also had a terrible fear within it... a nameless fear that strove to consume everything.. but Mikoto knew she had to keep going.. her Sisters.. all of them needed her..

"Yes Mikoto.." said the voice. "They need you... and I need you too... come.. and we can be together always..."

Mikoto could feel herself going dizzy as she wandered closer to Los Noches. "F....forever.....urgh....?"

"Yes..." said the voice. "Just you and me my love... my Lance..."

Mikoto saw Las Noches collapse into the sand as a handsome figure arose in front of her.. his skin pale and handsome.. his dark hair wild and untamed... his raven-black wings  spread out before her as his dark robes were even blacker then the skies of Hueco Mundo.

"You are mine.. forever.." said Asgawrath.

Mikoto's eyes opened with a start. Natsu was shaking her awake. "Hey.. Mikoto, come on, we have to get moving..

Mikoto shivered and got to her feet as she watched her breath turn into fog in the cold rectangular hall.. Grimmjow was standing only 10 feet away, his arms folded. "Come on.. we gotta get going if we wanna stay ahead of all the hollows and any other ressurected idiots like Zancrow that come after us..."

"That's unlike you.." said Mikoto as she stretched her arms. "I thought you'd like to take anybody on, no matter who they were or how many.."

"Sometimes it's better to assess the situation then fight blindly.."

"That's not something I thought I'd hear you say either.." said Mikoto with a sly smile. "Let me guess, Mira told you that didn't she?"

Grimmjow nearly tripped over his own feet. "Wh-what!? No!! That woman is nothing to me!! Just an annoying irritance!! I wouldn't follow any of her advice!!!"

"Sure you wouldn't..." Mikoto said. "How long have we been sleeping?"

"Who knows and who cares..?" said Grimmjow. "Here in Hueco Mundo, there's no day, or night.. we sleep when need to and we devour as many hollows as we can before they devour us... at least that's how it is before you become an Arrancar. But Hueco Mundo opperates by a strict Law of The Jungle rule.."

"But it's a desert.." said Natsu.

"No you idiot, I mean that it's survival of the fittest." said Grimmjow. "There are three levels of Menos Grande, Gillian, Adjuchas, and Vasto Lorde.. These three stages of a hollow's evolution is a testament to this law.."

'How so?" Mikoto asked.

"A Menos Grande is first created when masses of hollows all try to eat each other at once." said Grimmjow. "They merge together and become a mindless beast called a Gillian.. these guys are pretty much our footsoldiers... then sometimes.. one of the many minds within a Gillian will manage to dominate the others and become the controlling personality. That Gillian will then have to continuosly devour other Gillians to keep from regressing back to being mindless. If it gets eaten or bitten or a part of it's body is devoured by another hollow.. the regression will start... after devouring enough hollows.. the Gillian evolves into an Adjuchas.. The Adjuchas are smaller.. non humanoids usually.. but powerful and intelligent... but they have to keep devouring hollows or risk regressing back into Gillians.. and once they regress back.. their's no turning back into an Adjuchas..An Adjuchas can stop the regression though.. but only if part of them get's eaten by another hollow... but that would mean the Adjuchas can't evolve further into a Vasto Lorde."
