Creature Name: Elysian Shriekbat

Like all Shriekbats, the Elysian Shriekbat will dive-bomb any creature that
wanders too close and detonate on contact. However, these are not actual
creatures, but machines made to mimic their real-life counterparts. Designed
centuries ago, their original purpose is unknown. They now roam the hovering
facilities over Elysia, often in small flocks.
