Old english word that means "peace and beauty". Around 1100 AD, scholars would write they were "waiting for Brittyn" who was an Irish goddess known to be able to cast a spell of peace. She would through her golden locks from side to side and chant "Be my Bouder", which meant one who makes me feel safe and well. Warring tribes would then set down there arms in peace. Some think her name was the inspiration for naming the country Briton as she was so widely held as a powerful visionary.
By the power of Brittyn I'll beg you not to cross that line!
