Meadows - Represents the beautiful welcoming newbie friendly biome inspired by the green european countryside.
Black Forest - Represents the spooky forest where many european fairy tales take place.
Swamp - Represents the burdening anguish of european fiscal pressure. An unrelenting machinery designed to feed a mastodontic and insatiable creature, that raises above all the souless bodies rotting from the gangrene that is taxation. Awaken by the smell of hope and joy of an adventurer, still not suffocated by the despair from the life-sucking bureaucracy, and the gold in their pockets.
Mountains - Possibly just simple snowy mountains, that's all.
Plains - I think there's plenty of plains in Europe too. Maybe mediterranean, maybe baltic, maybe just agricultural land anywhere in within the continent.
