Always in Motion: Ambush on An'Kerra was a uniquely styled fan audio drama produced by Rayzur's Edge Audio. Written and directed by Nathan P. Butler, Always in Motion was a story formatted to allow the listener to choose the fate of the main character. Initially intended to be the first in a possible series of "Choose Your Own Adventure" audio dramas, Ambush on An'Kerra is to date the only fan audio drama of its kind to be produced.
