The Ember Concord Expanse is a broad Fiendkin homeland of treaty cities, half-tamed wilds, and layered planar crossroads. It stretches far enough to hold many settlements without feeling unified by distance alone. Travelers move between embassies, market enclaves, old family estates, and drifting frontier towns that cling to roads, rivers, and portal lines. Its people live by etiquette, bargain, and vigilance, because every border is also a conversation.
