Saracens - the most radical group among the Corsairs which set as their goal the destruction of all 5 houses.
In 450s after redeading full record of the history of Rheinland and the other four houses, they were outraged. No attempt had ever been made to locate the Hispania or its survivors. Suspicion that the other houses were behind the sabotage of the Hispania turned into hatred, and with a renewed determination, the sons and daughters of Crete took to the stars again.
Defenition of their flag, five stars and broken moon - 5 stars belongs to all Major houses that sabotage their "Sleeper" ship and as of reminds of their mission. Broken moon stay as remind of their bleak existence for four centuries and Great Houses should pay for that with blood.
The origin of the term "Saracen", exactly how and why they call themselves that, remains unknown. The suspicion that grew into irreconcilable hatred formed a separate subculture within this group of Corsairs.
