Highlanders/Hibernians continuity

For the last three or so years I've been paying attention to the lore, there were differences between those Celtic people who were born across the rift, and those who were born on Travance's side of the rift. What is happening with this? is there still cultural distinctions, or are they amalgamated?

I would like to know too... as the Hibernians were already established as separate of the Highlands.

Similar in culture but very different.
