Got another pair of Crumpleverse Neoclassicism pages, which I'm only posting together because they make better sense as a pair. If I get any sections of this which don't have maps at all, I'll post them in a separate thread because otherwise that's just being lame.
Final contrasts to the previous planet founded with such intent, Delphi. The latter had access to riches (even if their aims still exceeded their means) and more than anything wanted to recreate the look and feel of a past society they admired. Final, by contrast, was much more of a straightforward colony in its material culture (at least at first) and was created
for cultures historically subject to minority status, and/or disenfranchised. In intent, at least, the cultural and linguistic revival was much more the point than any attempt to make things
look like 17th century Ireland or Scotland.
NB: Erse is a very archaic word in our current language, and historically had ambiguous use referring to either Irish or Scottish Gaelic. This revival of the word on Final presumes that people got tired of using the term 'Scottish Gaelic' just as much as modern Irish folks have gotten fed up of people calling Irish 'Gaelic', and so revived an old term to fill the gap. 'Scottish' would be a bit disputed by Scottish English and Scots speakers, to say the least.
Final's description here mentions settlement by folks from Scotland and Ireland, but that by itself doesn't mean they're all going to be Gaelic speakers or particularly committed to a cultural revival if you're used to a 22nd century standard of urban living, this is part of why the intellectual forefathers of the colony had such a hard time getting a version of their revival to impact on a cultural level. Not to mention a number of the colonists were neither Irish nor Scottish, and some who were had never lived in Ireland or Scotland, adding to the number of different communities and assumptions taken onto the planet.
To elaborate on some of the different cultures mentioned in the graphic, or hinted at by the language family map, the Inglis live in North-eastern Alaba, which was historically home to most of those colonists descended from Scots. The Inglis are descendants of English speaking Scots, and the Modern Inglis language is not dissimilar to modern English- a fundamentally Gaelic language that's nonetheless heavily influenced by English spelling, loanwords, and some grammar. The Inglis tend to have Gaelic surnames but English personal names still mostly recognisable to a present day English speaker.
The Ceilta are not referred to in the graphic directly. They began as the neo-polytheist revival moment on Final referred to early on, which didn't have much luck when it came to persuading the general population to join in. But the Ceilta have always freely interacted with the Finalborn of other faiths, and are considered part of the planet's tapestry of differences. They may never have grown very large but they've solidified into a distinct culture with a proud, almost six hundred year old continuous heritage of practice. The specific environment of Final and that long a history of worship have changed the Ceilta's practices, and their mission statement. Ceilta is now both a spiritual and cultural movement, aiming to create a pan-Celtic culture suitable for interstellar human society, and their attempt to spread has reached far beyond Final; as of the 28th century it's now estimated there are more Ceilta living in other solar systems than there are on Final.
