World of the Garganta

I got this idea on thinking of how Cross disappeared and came back recently.
I am doing a little plot thing, even though it's not anything huge and it won't affect anything with the current plot at all, I promise, but, the idea was that, since Garganta is pretty much nothing, maybe like there is a world in there, cause, what happens if the garganta opens up and people like, fall in it or something. I imagine that something will happen and a world is created.
Well, the plan is, Mugen and Cross fought in this 'world' and Cross 'lost' but ended up winning his body and having full control over Mugen's powers and such. I want someone to help me sort this out into a mini plot. It was supposed to be done during the Lee event because it happened during that time span, but, stupid me, forgot the password to this account and couldn't do it :(

Is there any way that I can help?

I don't know, but with Cross beating the strongest guy within the garganta, well, so far, Cross has gained his power and possibly the ability to control the inner items of teh Garganta. Which isn't much, kinda just doing with it usually does and stuff.
But, just keep discussing it. I want to know ideas that i can use. I already made a post of it in My Dynasty so you all can get an idea as to what the fight will look like.

Well, you could read my thread in My Dynasty. I planning on having a new enemy appear though, and it's going to be unexpected-ish.

I'm not intrested in Hueco Arca. You know that. I've had it with all the stuff that happened there which changed everything now. Like you turning to a demon. that was a fail moment imo lol. Sorry if that sounded rude, didn't mean for it to. I just don't want a part of a past Hueco Arca as the account of someone not around during the event. Maybe Zero, but not Cross. -sigh, i'm just a very very cranky person. I appologize-

Explain how Cross' attitude changed, because his attitude was a big part of him. Also, is Cross really Cross, or is he really Mugen with Cross' Arrancar abilities?

What happened was, Mugen and Cross fought. Within the garganta, 1 year passed within the time it took for Lee's invasion and betrayel. Cross lost the battle and had Mugen inside his body so Mugen can live on. However, Cross overtook Mugen and killed him, keeping the bodies together forever, which is why he has had an appearance change. His personality changed because nobody was in the garganta world but himself and he was lonely and felt betrayed by everyone for not coming to help him. That's one reason why he isn't allied with Hueco Mundo.

Okay, I think that's it. You might want someone like Shiro or Mister E to spot you before you bumped into Kyouga though. You could also make the Garganta like the Dangai Precipice World.

I have decided to work on a mini story about the inner world of the garganta. I will upload it soon because I haven't started yet. But, I do know who the main characters are because it takes place during the Lee thing so here's the players so far.
Suzaku / Lavi
Lee Minamoto
Lasci
Ciel
Claire
Shiro
Kyouga
Mugen
Aki
Roukostu
Hanzo
Sanba

-If there are more, please update this list or edit it-
I am probably going to draw them and display what I think each player looks like in how I see them. I hope you'll like them.
