Bres and Cían were two Nocht, accompanying Princess Macha to The Ancient Gathering. Both were described by Sírlám the Scribe as tall as trees, "shoulders broad as wardrobes and appearing like monsters from a myth long forgotten", the latter mostly due to their hairstyle, typical for the Nocht: Lime Water, used to raise the hair up into a hairdo, that was tall and intimidating to the opponent.
They were also Selkie, who were able to grow moustaches and did so, caring for it meticulously. The older of the two, Bres, had a slightly longer moustache.
During the stay, the two of them wore a skirt-like apparel in order to protect from a cold (which was not there) and because they would see it as rude to make any man feel inferior to them as they were guests.
