From around the seventh century, the connection between Wales and the Old North was lost, and the focus of Welsh-language culture shifted to Wales, where Arthurian legend was further developed by Geoffrey of Monmouth.
Pada abad ketujuh, hubungan antara Wales dan Old North hilang, dan fokus kebudayaan berbahasa-Wales bergeser ke Wales, di mana legenda Raja Arthur dikembangkan lebih lanjut oleh Geoffrey dari Monmouth.
