Ourlon was pleased with being given work again, practice made perfect they said, but swinging his blade at the same things over and over again, overseeing his followers doing the same was starting to get stale, there was always more to be done by swinging a blade to slash living flesh, with the intent to kill, but even then, it was yet time for this.
