Earth is dying.

A mysterious phenomenon known as 1HD (One Hour Death) has covered Earth with a deadly fog that kills any living creature after exactly one hour of accumulated exposure.

To prevent humanity's extinction, countless Magic Towers suddenly appeared across Earth, each leading to a different world.

Etherly is one of those worlds.

Connected to Earth through a single Magic Tower located in Alaska, United States of America, Etherly is ruled by one of The Rulers. Free from the 1HD fog yet filled with unique ecosystems and dangerous native monsters, this world offers humanity a second chance—not through mercy, but through survival.
