is set in an alternate universe britain! i based my map off real kingdoms that did once exist in these places, some being celtic kingdoms, and others being part of the later anglo-saxon heptarchy. most of these place names are still in use to varying extents to this day.
i did use a load of artistic licence here though - sargentum never existed, it's purely fiction but it occupies a similar place (albeit completely different shape) to modern day london. the other town names are in their old english forms with a few exceptions, and welsh names in welsh, cornish in cornish etc
i'm just a huge fan of etymology so this was INCREDIBLY indulgent haha
edit: is this coming up blurry on other screens? i've tried larger and smaller versions and they've all come out blurry and gross, idk what to do
