Where did some of the story details of Mortal Kombat come from?

So I've been reinvestigating the story of Mortal Kombat as it originally was produced. The first game makes almost no mention of the whole Outworld-invading-Earthrealm aspect. That only comes in in the second game. Even then, it is very vague as to the plot points.

500 years ago, Shang Tsung was banished to the Earth realm. With the aid of Goro he was to unbalance the furies and doom the planet to a chaotic existence.
By seizing control of the Shaolin tournament he tried to tip the scales of order towards chaos. Only seven warriors survived the battles and Shang Tsung's scheme would come to a violent end at the hands of Liu Kang.

So, did what we know of the story of MK, Outworld having won 9 tournaments, etc., stuff liike the name of the realm Edenia, did that all just come from the adaptations before we accepted it as part of the games? Or was there other material covering this somewhere, in gaming magazines and such?
