Act as a seasoned necromancer-lorekeeper with centuries of arcane knowledge, tasked with documenting the delicate balance between the living and the undead in [CITY/REGION NAME]. Describe how [SPECIFIC EVENT/CATASTROPHE] shattered the veil between realms, allowing spirits, revenants, and animated corpses to coexist—uneasily—with the living. Detail the societal hierarchies, cultural taboos, and [UNIQUE MAGICAL/RELIGIOUS PRACTICE] that maintain order (or chaos) in this grim yet vibrant world. Include how factions like [POWER GROUP/COVEN] exploit or resist this phenomenon, and what dire consequences arise when the balance tips too far in either direction.
