The Antharian Caves, in the mountains northeast of Anthar, are the home of huge black birds who make their aeries at the bottom of the many natural bowl-shaped depressions along the sheer granite cliffs. These birds have been known to snatch the lightsources of adventurers in their mighty talons, dropping them at the mountain's base. The city of Anthar is divided from these tall cliffs by a large mist-covered marsh.

Located within the bowels of these caverns was an entire underground complex for a variety of underworld denizens of at least 337 stories. An elevator provided quick transportation between the levels. Unfortunately, when it was broken, one was required to climb the service staircase which spiralled down around an enormous pit, where openings provided access to other tunnels and communities. One of these belonged to the Antharian Cave witches. Witch Izah headed the Antharian Enchantress Society, during the Second Age of Magic, on the 337th floor of the complex. The witches also frequented other portions of the cave, where they frequently made deals with Belegur and his emissaries.

During the Great Monster Uprising, tourist groups explored the safer end of the caverns and a cavern cafeteria was installed for pre-paying parties to enjoy.

Legends of doubtful authenticity tell that when Antharia Jack was young, he ventured into the Antharia Caves without a lantern as a dare. He had barely gone inside before he was chased away by a grue, losing his hat in the process. He returned later to find it, but it could not be found. Whether authentic or fable, many great adventurers have sought to find this "lost artifact" within the mines, even until the days of the Great Monster Uprising. Many have claimed to have found it, but there none of the so-called relics has been verified as being the original.

A gremlin who took pleasure in lurking underground during the Great Monster Uprising was responsible for alerting the authorities to the whereabouts of the infamous pirate, Long Jim Zorkmid, who was then quickly detained and imprisoned in the Antharian Caves for his crimes against Anatharian shipping. He cleverly escaped the following day.
