Maglev rock.
A special rock that emitted a blue fluorescent glow and could float in the air.
It was fragile, scattering at the slightest touch, but would gather back together after some time.
This rock was widely distributed along the fringes of Pharloom.
It also existed in the Flame Capital, though the regional differences made the maglev rock here considerably harder.
Using this special maglev rock, the bugs of an ancient civilization had built a floating island called Sky Island.
By boarding an Airship at the Royal Airfield, one could easily surpass the flight limits of ordinary bugs' wings and reach the suspended Sky Island.
Large chunks of maglev rock formed the ground floating in the air. Even the greatest sandstorm or hurricane could not move it an inch.
This was the power known as a magnetic field.
No matter how violently the outside world churned, this floating island remained standing firm.
But why it had been built was lost to the distant past.
Theories abounded. Some said it had been created to provide the ideal experimental environment, while others called it a refuge built to escape the spread of the Void.
Yet none of these conjectures had any concrete evidence behind them. The only thing anyone knew now was that this incredible miracle truly existed.
Nothing more.
But as the years passed, the entire island was, in fact, crumbling little by little.
At first, there had only been tiny fragments, then sudden fractures, followed by an agonizingly slow disintegration.
Though the maglev rock used to build Sky Island was sturdy, it gradually lost its magnetism over time.
Perhaps the bugs who built it had believed their descendants could easily solve this problem. Sadly, they would only have been disappointed.
It had been left exposed to the wind and sand,
