So Storywise..

... I'm assuming the Horde is a massive army that likes to take things.

Because there's no background on the groups, and The Horde is the only place without a home.

I mean, from what it looks like...

I lead an army of like... the NPCs that get slaughtered daily...

Which would have been good to know before applying. lol

The Horde is the 'Monster Army' essentially the enemy to everyone. Not all monsters are considered evil and some are even accepted in society but for the ones that hold hate for the humans and wish to be the dominant race, the Horde is for them.

So I'm guessing that even in my "empire" There's good and bad ones.

So don't get attached to my NPCs.

So I'm like the Arrancar leader... and y'all can just kill as many Shinigami as you want. XD

Well controlling the Horde is your will actually. You can dictate the state of the Horde, it's basically just the monster alliance. If you want to become the enemy then rally your army against someone or you can just lay low or do whatever you want, you aren't immediately the enemy, the choice is yours IC.
