The First Swarm

Call a mythic swarm tied to a plague, migration, omen, famine, army, forest, city, god, or ancient hive. Define its principle with the GM: the swarm that devours a tyrant’s harvest, shields a people, carries a prophecy, cleanses a battlefield, or remembers the first nest. It can be ended only by Tier 10 swarm magic, divine intervention, or a story condition set when called.
