Game Overview
A living metropolis rides across the skies on the back of an enormous creature, turning city management into a fantasy adventure with genuine scale. The Leviathan’s Fantasy mixes settlement building, autonomous adventurer management, and story-driven expeditions across floating islands shaped by myths and local cultures. Its mood is colorful and imaginative rather than relentlessly grim, but the freedom to aid desperate characters, exploit them, or reshape their fates gives the world a welcome edge. Watching a carefully planned airborne city grow while colossal beasts drift through the clouds is the central attraction.
Your work begins with laying out districts, gathering materials, assigning jobs, and constructing the facilities needed to keep residents productive and supplied. Adventurers head out to distant islands to fight, loot, investigate, and bring back resources, while you influence their development through gear, abilities, talents, and recruitment choices instead of controlling every movement directly. These characters have individual traits and specialties, so building an effective roster matters as much as erecting another workshop or residence. Flight routes for the Leviathan add a strategic layer, forcing you to consider where to travel next and what risks or opportunities each destination offers.
The standout feature is the way exploration draws on stories that become physical places, letting you interfere with familiar fantasy scenarios rather than merely clear combat maps. Its broad research system supports radically different directions, including martial disciplines, spellcraft, occult practices, scientific advances, and immortal cultivation, with inspiration choices steering each run toward particular breakthroughs. That blend gives the progression more personality than a standard city builder, especially when unusual technologies change how your settlement and adventuring force operate. Players who enjoy the indirect control of RimWorld, the colony planning of Oxygen Not Included, or fantasy management games with emergent characters should find plenty to experiment with, though patience for systems-heavy automation helps.

Check that extraction completed and your PC meets the system requirements, including Version 11. Note any error message before choosing a fix. If it identifies a missing runtime, install the required DirectX components or Microsoft Visual C++ Redistributable from Microsoft.
My antivirus is blocking the game — is it safe?
A warning needs to be investigated; the download source alone cannot confirm that a file is safe. Keep your security software enabled and review the detection details. Do not run or restore a flagged file unless you have verified that it is a false positive. If you are unsure, leave it quarantined.
