We know that Beryl's mother lived in the forests, hating human society as we know it. Beryl prefers guns and knives to Magecraft. Artoria Caster is the Child of Prophecy who was chosen along with the “Staff of Selection”. She has known a different Merlin from us,
The Legend of King Arthur is set around 500 AD, but LB6 is called 'the British Lostbelt', which orients the lore of LB6 to something larger than Camelot. 'Fairy Round Table' & 'Avalon Le Fay' indicates that it is not the Round Table of Camelot, but a new Fairy Round Table.
#FGO Thank you FGO! The Knights of Round Table & Lancer Artoria are wonderful!
#FGO My biggest expectation with Lostbelt 6 is Galahad Servant. Lostbelt is a place where this can be possible. Obviously, it's a very big expectation. As Dantes says, wait and hope.
