Aerophins are native to Mirrodin. They are a species of flying artifact creature with a dolphinlike body and a translucent sphere for a head. They can fly fast and emit a powerful energy bolt from their bubble-shaped crania.
The Vedalken use aerophins as servants. Aerophins are fast, light, and aggressive. Because they can travel great distances quickly, the Vedalken send them to do their remote dirty work.
