Verse:Irta/An Indo-Iranian branch
Almost the same as our Slavic but it has Celtic loans instead of Germanic
It evolves in Irta's British Isles (before English), specifically Scotland (hence the name Albionian - the idea is "what if Scotland had been settled by Slavic rather than Goidelic people); migration to Tricin happens at the same time as English and other migrations, because of the Remonitionist Reformation (Remonitionism is especially common in Albion)
