Look at the Myth map. What do you see. Gower surrounded by Ghols to the East Trow to the North what was The Dark to West and South. Its hardly going to survive 50 years between the Fall of Muirthemne and the Defat of Balor with that kind of opposition. Just because it isn't mentioned in game doesn't mean it didn't happen.
Also if there was something there when Alric was so close you think he would have gone there briefly for some much much much needed reinforcements. But he didn't, why? Because there were none.
