Embryo Engine

The Embryo Engine (卵パック) is a construct of C0DA developed by Godd Howard in order to provide a framework for his created world of NieRn. It has been cracked and is showing its age with time, but Godd insists that it still just works. Some speculate that Godd Howard was emotionally attached to the engine and was proud of seeing it thrive for so long before he retroactively become a slave to his own creation, The Skyrim Scrolls, where now it's clear that the engine will never be replaced by another construct due to complacency. 
The Embryo Engine fit nicely into the Bitchmobile (an old egg with four wheels and still keeps it running to this day, albeit with sputters that warn of a day where Brandonkind may finally overcome Godd) after Godd Howard stole it off of the Vice Squad.
