During the S.1190s, authorities started to receive reports about young children around the age of 5 being kidnapped. The incidents were most common in Calvard.
International investigation team
Authorities decided to establish an international investigation team to find a common cause in the cases of Calvard and its neighbouring nations. The investigation team consisted of the police department and army of each nation as well as representatives of the Bracer Guild.
They found that the kidnappings were carried out by a cult that referred itself as the D∴G Cult and that it was using Gnosis for a greater purpose, since "D∴G" means literally "D therefore Gnosis". They also concluded that it involved dozens of children spread over more than ten lodges, where they experimented with artifacts, summoned devils and experiments on living people, all surrounding the drug Gnosis.
On behalf of the Crossbell State Police Department, Arios MacLaine, Sergei Lou and Guy Bannings were in charge of the lodge near Altair, a border city between Crossbell and Calvard. Guy Bannings managed to rescue Tio Plato, 8 years old at the time, who was debilitated but still in a far better shape than children in other lodges who had been repeatedly exposed to experiments. Many could no longer be saved.
Although each lodge required its own approach from the operation, the outcome of each raid would be consistent. The majority of the arrested cult members committed suicide, the rest suffered major mental breakdowns. The investigation team also discovered a vast amount of heavily mutilated corpses of children that was experimented on in the name of a "ceremony".
The operation successfully managed to exterminate the body of the cult. Some cultists managed to escape, however, and awaited their chance for the cult's revival from the shadows.
Other extermination attempts
Separately from the D∴G Cult Extermination mission, there have been other efforts to exterminate the cult. In S.1196, on behalf of Ouroboros, Leonhardt and Joshua Astray raided the lodge "Paradise" where they found Renne Hayworth and took her in.
Surpeme commander Cassius Bright was promoted to the highly extraordinary bracer S rank for his efforts. The mission itself was locked away as a top-secret mission because of its sensitive contents.
There were dozens of victims reported. All of them young children of approximately 5-years-old, the majority already dead and/or heavily mutilated.
