The Fire Moth was an organization of the Old World that has since been wiped out prior to the current civilization. Its purpose was to serve and protect the last human population but failed and was wiped out by the last Herrscher of that era.
The Fire Moth was a rebel organization located in Sky City, which was founded by human beings in the Old World. The mission of this organization was to protect people and eliminate Houkai threats.
However, when the 14th Herrscher destroyed the Old World, this organization was also wiped out.

Professor Mei researched quantum mechanics and used its capabilities to eliminate Houkai threats.
The Solider Project
When the organization discovered that the 7th Herscherr was too strong against any normal human, Professor Mei started the Soldier project in order to improve human strength by fusing the human body with the DNA of Houkai beasts.
Kevin Kaslana was later fused with the DNA of the Emperor-class Houkai beast, Parvati, giving him the power to control ice, and also make his body temperature drop to -30°C, making anybody standing near him turn cold. With his newfound ice powers, he used Judgement of Shamash to defeat the 7th, 9th and 11th Herscherr.
The God Key Project
Mei and Prometheus A.I. created this project in order to make God Key weapons, and use it against Houkai. Eleven powerful God Keys were made in total before the organization was wiped out. However, only 7 out of 11 God Key weapons were found as of today.
This is the last project created by Professor Mei to implant stigmata to the human body. Mei knew that the 14th Lawmaker would later destroy their civilization, so she left and preserved a batch of girls called the 'pioneers' in which Fuxi, Nuwa, and Fu Hua was included in, with stigmata implants with the goal of guiding and protecting the next generations to come.
