True, the DFRPG isn't real life. I can edit my comment if you like, I'm aware that the majority of people on this forum are American and I'm also aware that religion is a sensitive topic. I'd prefer not to edit my earlier comment though as I feel my points were relevant for a fair and balanced view and mentioning Hashshashin or Sufi magic for Islamic knights is unfair when the DFRPG Christian Knights aren't influenced by the spanish inquisition, the crusades, witch burning or any of the more negative facets of Christian history.
I always forget irony and sarcasm don't translate well online.
Also, I think whatever you come up with, much of it will have to be invented totally, just as the KotC in the Dresden Files were pretty much totally made up. On a name, something based around the concept of the (greater) jihad or the jambiya (the knives Muslims wear)?
