The Kingdom of Dyfed (Welsh pronunciation: [‘dəvɛd]) is one of several Welsh petty kingdoms that emerged in 5th-century sub-Roman Britain in southwest Wales based on the former territory of the Demetae (modern Welsh Dyfed).
In the year 360, a sudden series of coordinated raids by the Irish, Anglo-Saxons and Picts began. These continued as the Irish colonised the Isle of Man (formerly Brittonic-speaking like Wales was) and resulted in a short period lasting until the 5th century during which Old Irish was spoken in the region: twenty stones dated to this period have ogham inscriptions. One bilingual Latin-Irish stone in Castelldwyran, near Narberth, has the name Votecorigas written on it; the wordier Latin inscription is Memoria Voteporigis Protictoris, giving him the title “protector”, a late Imperial Roman title given to nobility.
Dyfed may have originally occupied the area that bordered the rivers Teifi, Gwili and Tywi, and included contemporary Pembrokeshire, the western part of contemporary Carmarthenshire, and with the town of Carmarthen. Dyfed eventually comprised at least seven cantrefi: Cemais, Deugleddyf, Emlyn, Cantref Gwarthaf, Pebidiog, Penfro and Rhos, with an approximate area of about 2,284 square kilometres (882 sq mi).– wikipedia
As previously discussed, the “Irish” maps to Hibernian elves and half elves, “Anglo-Saxons” maps to Britannic chaos hordes, and “Picts” maps to Caledonian halflings. Needless to say, fair-folk positive kingdom ruled by elvish noble-houses, in the age of Chaos.
The settlement that grew up around the monastery was called Tyddewi meaning “David’s house”Note on Saint David’s
