EA Blodwold, Thirsting Trees
Blodwold is a germanic/slavic/celtic nation worshiping trees and thanking them for all their hard work with human sacrifices. Your druids can sacrifice those pure of blood and during those sacrifices a sacred tree may awaken. That tree can then perform rituals to grow in power. Like Pangaea you can also grow bramble forts in forests, but by enticing the plants with blood rather than nature magic. You also have access to some nifty summons. Also don’t forget to gather your chieftains and druids to elect a King !
The nation is inspired by the Roman accounts of Druidic and Germanic human sacrifices, particularly the grove of Fetters. The clothing and overall look is somewhat inspired by the movie Midsommar.
