The Sinclairs were a family which were tasked to deal with the Cultivation Outer Domain.
But instead of fighting them like the Ravencroft family, The Sinclairs forged bonds with them.
The reason Cultivation Outer Domain was the first ally of the Human Federation among the Eight Outer Domains was largely attributed to the Sinclairs.
Now, two hundred later after they first set food on Earth, the Eight Outer Domains had established various bases of operation on Earth.
The Sinclair Family's Headquarters were situated in the main base of operation of the Cultivation Outer Domain.
Just like how the Ravencrofts had their members in the Human Federation, the Sinclairs had an even higher number of people in positions of authority in the main base.
However, their authority was only limited to the main base of operation.
