Star Trek: The Original Series: The Antares Maelstrom

Baldur-3 is an obscure planet just beyond the outer fringes of Federation space, until a group of struggling colonists discover vast quantities of the energy source pergium beneath the planet’s surface. An old-fashioned “gold rush” is now underway—a chaotic situation, as neighboring planets and space stations are vastly ill-equipped to deal with the flood of vessels and aliens competing to get to the planet in time to stake their claims. Although Baldur-3 isn’t technically under Federation jurisdiction, Captain James T. Kirk and the crew of the Enterprise are soon diverted to deal with the crisis . . . one which lies on the other side of the dangerous area of space known as the Antares Maelstrom.
