Gustav shared the map with the masked man, and the masked man shared the holographic projection of the device.
From that day, they started working together to investigate the border.
They shared communication devices so when something happened, they'd be able to inform each other.
At the end of the day, they'd compile observations.
Gustav didn't inform miss Aimee about this collaboration. Instead, he investigated the mercenary agency the masked man was sent from himself.
The agency was called, Cloudbeaks and they were pretty popular in the southern lanterns city, which was on another continent.
This broadened Gustav's horizons as he was able to figure out that there were also private agencies that dealt with the situation of mixedbloods and mixedbreeds apart from the MBO.
These agencies were mostly sought out by those who could not contact the MBO for their issues and those who had illegal issues to deal with.
