It wasn't too surprising to hear about, there were several races throughout Equestria that didn't have marks of their own. Hide dying was becoming more popular, lots of ponies liked having intricate symbols, and works of art painted into their fur. It was just a shame it wasn't permanent. Unlike 'branding' which was practiced among the Minotaurs, and Cattle races. Usually only those that belonged to a large clan received a brand, however, it was considered a poor emulation of the Pony race's naturally occurring custom. The Griffins and some of the younger ponies were picking it up as well, despite knowing that it actually was permanent.
