The Fellowship of Order was the ancient sect that sparked the creation of the Imperial Order.
The Fellowship was dedicated to doing the work that they saw as being the Creator’s will. They believed that those born with a need are to be served by those with the ability to help.
It was seen as a grave evil by the Fellowship for a person to live their life for themselves and not give themselves over to others entirely. Under the Fellowship, hard work was done to benefit the whole and very little was given back to the person doing the hard work.
They were willing to commit any number of horrors in the name of their twisted fun-house mockery of altruism, utterly ignoring and violating the very first principle of the altruism they claimed to be spreading: empathy.
