Excavating facility dug out of the Callaegh Steps. These mines single-handedly supported the modernization of Lucian architecture: the Insomnian skyline is composed almost entirely of the skyscrapers constructed with Balouve-made building stones.

While some sought employment of the mines as a more traditional means of achieving economic security, many hoped to strike it rich by capitalizing on rumors of rare metals hidden within the limestone walls. People flocked to the area, and a bustling mining town arose in turn.

The pipelines winding across present-day Leide are a testament to the centrality of natural resources like oil and gas to the region’s economy, while the trade of mineral resources has all but dried up. After the daemons made the nest of the mines, the miasma they produced began eroding the walls and tainting their composition. Before long, the area was deemed unfit for excavation, and the mines closed for good.

• Found in the mountains to the southeast of the Longwythe Rest Area in southern Leide.

Enormous tower constructed millennia ago by the ancient civilization of Solheim. Built from sturdy stone and special metallic material, the structure weathered the catastrophic War of the Astrals and still stands to this day none the worse for wear.

During the peak of Solheim’s prosperity, its sphere of influence extended across all the lands of Eos with Duscae and Cleigne at its center. Scholars suspect Costlemark Tower helped solidify the nation’s hold on the continent, possibly serving as a military base of operations.

The outer walls of the tower glow red when night descends upon the Fallgrove, and the entrance to the structure is revealed. Intrepid adventurers have attempted several expeditions inside, but nearly all were driven away by the hordes of daemons dwelling within. Instead, most groups simply resign themselves to exploring the other ruins around the area.

• Found to the southeast of the Cauthess Rest Area Outpost, in the Fallgrove sub-region of Duscae.

Flood control facility once under direct control of the royal family. The series of pipeways boasts the same processing power as the sewage system of Insomnia, utilizing the same advanced technology.

First, the channels would collect rainwater, groundwater, and industrial wastewater from the area around Ostium Gorge. The water was then processed and preserved as a valuable natural resource for the notoriously arid Leide region. With the reduction of the Wall, however, also came a release from the royal control, and the facility soon ceased operations.

At present, the sewers serve as a nesting ground for beasts and daemons that presumably snuck in through the cracks in the now-defunct pipelines. Freshwater fish that flooded into Crestholm have also formed their own ecosystem in the reservoir above ground, a pool known as the sole fishing hole in the whole Leiden mainland.

• The Crestholm Channels can be found just outside the gates that lead to Insomnia, in the Leide region.

Series of caves situated in the once resource-rich Schier Heights. The area’s fertile soil and natural springs coupled with the warmth of the Meteor made for an ideal environment in which crops thrived and agriculture boomed.

Unfortunately, the great war had a considerably deleterious impact on the region. The kingdom used the high ground as the strategic base of operations, but the lack of ventilation in the caves made the empire’s toxic weaponry all the more effective. Poison seeped into the earth, tainting the soil and turning the land completely infertile.

Even veteran hunters hesitate to explore the caverns, now overrun with daemons. The only folks who venture inside are the most foolhardy of fishermen, led there by rumors of a reservoir deep underground that acts as home to some real whoppers.

• Found at Schier Heights, located to the south of the Duscae region. You must leave the car by the road and venture into the trail to reach the cavern entrance.

Grotto tucked away deep in the woods of Malacchi Hills. After a recent string of incidents involving a speaking serpent who absconded with several small children, nearby residents dared not approach the mouth of the cave.

In their despair, the citizens called upon the aid of the former Oracle, Sylva Via Fleuret. After luring the snake-like daemon into the hollow, the Oracle trapped it inside. While no other kidnappings have happened since the sealing of the cave, one can still hear the hissing wails of the serpent within.

Perhaps coincidentally, several eyewitnesses say they spotted a woman marching toward the grotto a few weeks before the first incident was reported. The woman in question had allegedly lost her baby to a band of daemons and was presumably off in search of her stolen child. Any connection between these events, however, remains purely speculatory.

• Found in the Malacchi Hills, located to the east of Wiz Chocobo Post. You will visit here as part of the story when looking for the Ramuh Summonstone.

Fabled “waterfall cave” tucked away behind Callatein’s Plunge. The waters spilling forth from Loch Thriocess conceal congealed caverns whose winding halls have vexed many an adventurer hoping to plumb their depths.

A legendary sword connected to the royal family is said to slumber within the recesses of the cave, but its existence has not yet been confirmed. Although countless hunters have attempted to follow up on these rumors, the monstrous midgardsormr slithering around outside the grotto has served as a strong deterrent.

• Found to the northwest of Cleigne. You must go down to the stream below and follow it to the cave entrance.

The Keycatrich Trench is a long-abandoned dungeon located in the Leide region. It was once a prosperous mining site, but has since been overrun by dangerous monsters and fallen into disrepair.

The Keycatrich Trench is a sprawling dungeon consisting of several interconnected tunnels and chambers. The layout is labyrinthine, with many dead-ends and hidden passages.

• Found to the far north of the Leide region, in the Keycatrich Ruins. You will visit this dungeon as part of the Main Scenario.

Densely grown jungle feared by many as the alleged home of “the Witch of the Woods.” Hunters hoping to venture inside and verify the claims for themselves have been met with resistance from the higher-ups at Meldacio HQ, who forbid any of their employees to enter the forest.

Researchers, however, are free to explore the forest as they please, and many have written extensively about the flora and fauna found therein. The thicket is rich with rare ingredients like the malshroom and other plants used in herbal medicine. The abundance of elemental mineral deposits also seems to suggest an environment ideally suited for magical synthesis—a strong reason behind the aforementioned rumors.

Others have reported sightings of an enormous unidentified beast dwelling in the heart of he grove, but such assertions have been dismissed as mere hallucinations caused by toxic spores floating throughout the forest. Nevertheless, those with penchant for the fantastic insist the monster is real, spreading word about “the Witch’s pet” to all who will listen.

• The Malmalam Thicket is home to the Tomb of the Pious.

Located in the southwestern part of the Cleigne region in the game’s world of Eos.

Ancient Solheim training grounds situated in southwestern Cleigne and shrouded in mystery. Hidden among the mountains and conspicuously missing from all conventional maps, these ruins appear to have been all but forgotten in the modern age.

Traveling the world is sure to open one’s eyes to the sheer variety of climates and cultures around Eos, but the one thread tying all lands together is the presence of peculiar stone structures. The toppled towers and shattered statues seen across the continent are testaments to the artistry and ingenuity of those who came before us, and Pitioss may indeed stand as Solheim’s crowning achievement.

But the most incredible aspect of ancient technology is its ability to seemingly manipulate time-space as we know it. Based on our current scientific understanding, every bend in the fabric of our universe must be counterbalanced elsewhere—our scholars suspect these ruins might be the space in which those interdimensional kinks are worked out.

• Located in the northwestern portion of Cleigne

In order to get there, you will need the Regalia Type-F, which is only accessible after completing the main story. You need to fly into the region with the dungeon and land on the strip of road to the south. The dungeon only opens at night and there’s no enemies inside.

For more information on this dungeon and how to unlock it, visit the Pitioss Ruins page of the main guide.

Stone mausoleum built by the ancient people of Solheim, who saw fire as a sacred symbol of life. The people paid homage to their patron saint Ifrit at the Rock of Ravatogh, and recent academic studies suggest the people’s devout faith was a driving force behind the advancement of their civilization.

If one were to hypothesize that water, in turn, symbolized death among the people of Solheim, then it stands to reason that they established their space for venerating the souls of the lost beside an enormous lake—the Vesperpool.

Those brave enough to enter the tomb have reported a wide variety of traps presumably laid to deter grave robbers. More interesting, however, is the design of the mausoleum interior itself: the emphasis on water and fluidity seem to support aforementioned theories about Solheim civilization’s conception of life and death.

• Found to the northeast of the Vesperpool sub-region in the Cleigne Region.

The Myrlwood Dungeon is a dense, dark forest located in the Cleigne region of Eos. It is home to a variety of dangerous creatures, including flans, treants, and mandrakes. The forest is known for its unique lighting and eerie atmosphere, which can make it difficult to navigate.

• Northwest of the Cleigne region, to the west of the Vesperpool.

Emblematic volcano situated in southwest Cleigne. Often cited as one of the finest sights in all of Lucis, the mysterious mountain seems to have frozen mid-eruption, and serves as a popular attraction for tourists and photographers alike.

The steep incline has sent many would-be climbers tumbling back down—sometimes to their doom. Picture-takers who persevere, however, are treated to some spectacular shots around the mouth of the volcano.

According to local legends, the body of Ifrit lies deep within the volcano. Drawn by these tales, devout followers of the fire god have made the pilgrimage to Ravatogh in order to pay their respects. The empire also launched a series of expeditions into the mountain several years ago, but their aims were never made clear.

• Found to the west of the Cleigne region, in the Ravatogh sub-region.

Circular crater created when the Meteor crash-landed into the middle of the Mencemoor in the age of the gods. The impact shattered the earth, leaving a bowl-like basin that inspired the site’s nickname.

The asteroid never hit the ground, however, as it was intercepted by the Archaean, who now slumbers with the rock upon his back. The round pits that pepper the Duscaen landscape are said to have been formed by bits of the Meteor that splintered off upon impact. One such meteorshard now serves as the primary energy source of the power plant in Lestallum, which converts the heat from the fragments into electricity.

The people of Duscae have a particular reverence for Titan—not only for shielding them from the Meteor, but for indirectly providing them with the energy that supports their lives as well. To this day, devout disciples still flock to the Disc, braving the treacherous terrain in order to pay homage to their patron saint.

• Found in the center of the Duscae region, you will visit this story dungeon as part of Chapter 4 in the story. The area will then become inaccessible after the events there.
