After all of the media crazyness we have had lately i've been thinking about all of the realms interacting in MK:D, and i have come with some thoughts about them:

Earthrealm: as you know you live in it (), and what i dont get is what makes Earthrealm so Special and hard to conquer,what makes big demons and gods to want control over it, why is it so great and why is it more important than opther realms.

Outworld: This is the merging relams that absorbs and mixes up with other realms such as The Vampire realm and before , Edenia, Shao Kahn was the emperor of this realm for many years, now the DK has returned and has taken his place back as the ruler of the Outworld, but what makes this realm the basis of all of the Demons and Powerwise baddies?, wouldn't it be more correct if Netherealm was?

Nehterealm: as it name states, the realms of all the things that oppose Rightness, the realms of the Onis, the demons and the restless souls, this is the realm that truly wants to conquer them all and unveil the darkness and insanity among the others.

Orderealm: We dont know much about it, but as it's name states, its supposed to be the Realm of Order, of justice, opposed to the chaos and netherealm, but hwat i wonder is why is it protected by a killer and mercenary as Darrius, what does this realm has to offer us? we will se but this among the Chaosrealm will have a heavy weight into the story.

Chaos realm: We no nothing about it, we may especulate that Hotaru is from this realm as he is the nemesis of Darrius.

Finally what is that that makes the realms have balance? Elder Gods? i dont think so, an even greater force? maybe, and as you know this must be the decesive battle in between the defenders of the realms (no pun intended) to save their lives against this big threat or falling apart.
I think there should be as well alliances in between the realms just to be more Stronger. Your Thoughts?.......
