Llanedeyrn (English: Ederyn Town) is a Welsh colony and oversees territory in the northern region of the Doggerland Bank. Welsh settlers landed in the area in early 3025 with the support of the Prince of Wales navy vessel, constructing an initial settlement along the southern bank of the Northern Sea, south of the Pontifical States. It was formalised in charter on 18 April 3025 by the Prince of Wales, who proclaimed it as the first "fully-Welsh" oversees colony. The colony was named for the Prince of Wales himself.
On 18 April 3025, the colony was made permanent, with Gabon Gethin appointed as Territorial Governor.
