There are certain Asian families who are loyal to the Illuminati who have perverted White Lotus. The assassins that serve this family try to kill White Lotus assassins. It's basically a white hat vs. dark hat war. When an assassin becomes loyal to the Illuminati either by being programmed, bribed, becoming addicted to drugs or by not having any moral fortitude they become a part of the White Dragon Society.
Various insiders have talked about various Dragon Groups. Groups such as the Red Dragons or the Green Dragons don't actually exist. These are lies that the White Dragons tell insiders in order to give the perception to people in the West that they have a lot of power over Asia.
Assassins have the ability to change the geopolitical situation in any given country. For that reason, in order for the Illuminati to control the world, they have to kill or corrupt all of the assassins.
