Get Rid of Fog

How was fog created?

Before the dawn of Aethasia, when the Great Engineer first came to the land, it swirled with mist. The Great Engineer saw its potential. He infused the mist with Aether, and through it, created Aethasia. People from everywhere answered his call and came to dwell in the land. Out of all that came, Lucky was one of the few chosen to be an apprentice of the Great Engineer. He became interested in Aethasia's creation. However, he didn't realize that Aether was the force behind it all. Instead, he became obsessed with the mist, which led him to resort to selfish and dangerous experimentation on it. These experiments failed to produce the power for which Lucky yearned, but they did produce the sickly fog we know today. This fog fed Lucky's jealousy and hatred against the Great Engineer. Lucky revolted and he got a bunch of people to join him. If the Great Engineer had wanted mere servants, he would have stopped Lucky and the mob. But the Great Engineer wanted the people to love him because they really loved him, not because they had to. The Great Engineer looked at Lucky and the mob in His throne room with pity and sadness. He left Aethasia and took the Aetherlight, the source of Aether, out of the Great Engines. Because there was no Aether to keep the fog out, the fog came in and invaded every part of the once-beautiful Aethasia.

How can we get rid of fog?

The Resistance must find all of the old Great Engines, repair them, and fill them with Aether. Once the Great Engines are running, they will begin to sweep all of the fog away. Currently, there are three engines:
The Town Square engine (Ep. 1), the Engine Bay engine (Ep. 2), and the Snowmoorian engine (Ep. 3).
