I have read from the web and the Camarilla book that Banu Haqim are part of the sect. I also read that they refuse the Ministry (and betray them).
But I don't understand why. Banu Haqim are known diablerist, which the Ministry isn't. Plus the Banu Haqim are just assassins and sorcerers (which the Camarilla has already).
Can you help me to understand?
