I've been reading quite a bit about Wales lately and began to get quite fascinated with its history. Naturally, I've been wanting to put this question on here for quite some time. With a PoD past the year 1200, how is it possible to have the Welsh at the very least control all of modern Wales and survive as an independent nation free of English domination? And beyond that, is there anyway for the Welsh in the era to expand beyond their borders and take much of England as per the "Mab Darogan" prophecy of a hero who drives out the Saxon/English invaders? Doesn't necessarily mean taking all of England, just want to know if any of you think any conquest even over time is possible.
