Makes sense to me

Actaully Tobias said that Outworld and Edenia re 2 seperate realms. And Kahn merged Edenia to become part of Outworld

Literally, the article written by Tobias says:
"[...]The Fall of Edenia -A civilized realm known as Edenia was once a living planet simular to the earth, it was ruled by King Jerrod and Queen Sindel -Edenia used a fighting tournament to defend itself against invaders -The dark emporer known as Shao Kahn managed to successfully invade Edenia and take the life of Jerrod, just shortly after the birth of Princess Kitana -Kahn then sapped the realm's energies, causing Edenia to become a large wasteland known as The Outworld [...]"

If you have seen another article, please tell me cause I would like to compare.

If my theories are correct, this story must bring Shao Kahn back to face Jerrod in Mortal Kombat.

You must also know that in the early MKDA development there was a list of rumored characters like this:

Rumored Characters:

Kung Lao, Probably
Liu Kang, Probably
Goro, Probably
Sub-Zero
Scorpion
Master Châng
King Jerrod
Chow Kang
Shao Kahn
Kabal
Kitana
Nimbus
Fujin
Noob Saibot
Baraka
Smoke
Sub-Zero's Sister
Shang Tsung

Master Chang was Liu ́s master, so he finally appeared, named Bo Rai Cho.
Chow Kang, Liu ́s brother didn ́t appear.
Baraka,Smoke and Nimbus didn ́t appear.
As you can see the rest of the others appeared in the game or in the plot, also if we consider Frost as "Sub-zero ́s Sister" meaning not to be his "official" sister but a female similar to Sub.
So we have left Jerrod. Obviously, if it was to appear in MK5, it must had been resurrected... For me this list is quite accurate.

For the Tobias ́ MK Story.It is in "Historia".

Not bad points, but IMO i really dont think the DK is Jerrod. From what we've heard, the dragon king was once a very evil being that wanted to rule all realms. He would brutally slaughter his victims, and he had an undefeatable army of 666 soldiers. He also came before kahn. Jerrod was the ruler of edenia along with sindel, IMO it seems like he was a good person with no cruel intentions.

I think the DK is the DK and nothing more. I think he will have a evil mind just like kahn, even worst. From everything thats been said, he seems more evil and intriguing than kahn. The DK was the original ruler anyway.

BTW, i seriously dont like the idea of Jerrod being the DK. IMO it seems cheesy. I do like your theory though.

Thank you for sharing your oppinion.
I do appreciate any of your comments.

I will admit that your theories are interesting. But there were some artricles posted before MKDA came out. I don't know if I can find them now. But Edenia and Outworld aren't one and the same. Kahn has conquered many realms before he reached Edenia. And when Kahn was defeated, Edenia and Earth And other unknown realms seperated from Outworld.
