The monastic order
which was the driving force behind the Spanish Inquisition
. Heavily interested in purging heresy
, they were the ones who led most of the burnings and torture

There fighting colours are still black and white. The motto of the order is simply 'veritas'. Most famous Dominican was probably Thomas Aquinas.
Eventually, their role as the favourites of the nobility was overtaken by the Jesuits.
