A story behind "Die Mutter"
日本語(Japanese): https://fusetter.com/tw/LLjEmhCI
The namesake of the title is "The Great Mother" by Carl Gustav Jung. It's called "The grosse Mutter" in German because he was Swiss. That of the machine "Die Grosse" is also by that.
The Great Mother is treated as a symbol of embracing, spoiling and ruining the children, and independence from her is treated as one step for them to become adult.
As an aside, "das Vater", which appears in the deepest part of the Floor S, means "the father" in german.
However, the article "das" is used for a neuter noun so originally "den Vater".
That means the father is an inorganic existence in this context such as Heidegger's "das Man".
The shape of The Main Chamber is based on an uterus, the Recovery and Machines chambers correspond to the ovaries, and the positions of Floor A and S are located are the uterine ostium.
The main characters create lives with Die Mutter, and they were also reborn and grown up a lot of times inside Die grosse Mutter until they can go outside.
Their names SEED/SEDE are both English words, and those are called Samen in German.
In the first place, the reason they came to do that was mentioned in the second ending: The "bomb" destroyed the environment entirely to the point of extinction of living things.
A certain country presumed the situation and it prepared some hibernating "subjects" including the two in the facility.
Restoration of an environment, which is so distorted that the shape of the earth changed, takes so long that the lifetime of one person is not enough.
Therefore, they established Die Grosse and Die Mutter that allows a person lives by itself to manage resource at a low cost.
"Mankind-M/F" of the second ending was a symbol of those who could not stand on their own and chose to hurt people with a desire for control, and it was a metaphor for the factors starting the war.
The happy ending for this game is that the day comes when they meet other subjects in the recovered world and become a mother and a father themselves without relying on Die Mutter.
Best wishes,
- Your real "parent".
