Thanks,thanks.I read all of the theories here and some of them are interesting and I don´t agree with them.
But there is no problem with that.I came to the forums not just to post mines but also to read others I hadn´t thought about.I wanna to discover and to let others discover.
By the way now I will tell you what I think about the code.
Gardens were created by people from Esthar .
So,Either the code was a memory of the greatest creations from estharians (like when you create a keyword that is familiar to you) or...
the number is a date related with JME and the MD level.
Ragnarok is a vehicle like the Garden and it could have a MD level place.
I have a theory about Balamb Garden related with the level.
I think all vehicles that travel to places you can´t reach by foot (Garden vessels,transcontinental trains,Lunar base,the missiles themselves,the Lunar Gate Rockets,Lunatic Pandora,etc...) have a MD level.
A MD level might not be a place but a mechanism of some sort.
It has a so deep meaning that it was hidden and appears like a code on the Ragnarok.
I think I know what it is.
Ultimecia´s castle was also a vehicle of some sort (think about it).
I think she wanna to use it like a SPECIAL vehicle and then constructed a MD level on her Castle.
