Altria is perhaps the most iconic character of the Fate franchise, and, at least in this universe, the true identity of the legendary warrior-king Arthur, under whose reign Britain enjoyed a brief respite from the chaos tearing the rest of Europe apart. She originally wielded the Caliburn, the sword she extracted from a stone as proof of royalty, but after its theft she received her main weapon, the Excalibur, and later Avalon, from the Lady of the Lake.
