But it is an Indo-European take on the evolution of languages which in a sense can be biased. The finno-ugric languages predate Germanic ones in Northern Europe. Also Finns and Estonians hold that they did not migrate to their present territories but they have been living there from times immemorial long before the arrival of Germanics . Might be that migrating Indo-Europeans tribes squeezed to North Finno-ugrics like Samis (Lapps)
Before people start to complain that this doesn't include all "old world" language families, it should be noted that this is from a webcomic set in post-apocalyptic Scandinavia in which the only known surviving languages are from these families with the specific goal of illustrating why Norwegian, Swedish, and Danish are sort of intercomprehesible and why Finnish is radically different.
