The Akiro cluster (pyro cluster alpha) is a dense asteroid cluster on the Pyro system. Situated in the L3 Lagrange point of Pyro I, the asteroids periodically move closer to the planet or farther away from it as they travel around their sun. Most were stripped of their most valuable minerals by Pyrotechnic Amalgamated and other companies, but some small mining outfits have been known to search the cluster for undiscovered troves.
