Babylon 5: River of Souls

Captain Lochley now has solid proof that Garibaldi is a disaster magnet: when he comes to the station to meet with one of his new company's subordinates, she's being sued by the owner of an illegal virtual reality "holo-brothel" and besieged by Soul Hunters looking for one of their soul vessels, this one containing the souls of the long-lost Ralga alien species. An archaeologist brought his most recent find to Babylon 5: an orb containing one billion souls of an extinct race. When a Soul Hunter arrives to recover the souls, they escape and wreak havoc throughout the station, leaving Lochley, Zach, and Garibaldi to save the station.
