The Cisterston Order and the Rule of Life

The Cisterston order was of order of poverty, an order of work similar to the Benedictines. Their symbol was a simple black and white flag; their crest was two dudes sharing a horse because they couldn't afford two horses. The Red Cross becomes part of their symbol a little bit later on. And then you've got the blue and white cross of the hospitalers, the red and whitecross of the Templars. Later on a rival military order called the Two Tonics get started and they are Germans. They're black and white. Did they sing?
