[…If, as the ancient texts record, the capital of the dwarves ‘fell’ into the sky, then rain there would also fall towards the ‘sky island.’ Therefore, the clouds would not scatter and would eternally travel with the sky island, and because of this, a great ‘Eternal Cloud’ would have formed around it. From the School of Non-Human Cryptoarchaeology - A Defense on Why the Sky Island Cannot Be Observed.]
Head of the Doloren school admired the old thesis while reading it on the airship deck.
“They were almost right. People from the old days weren't all fools.”
But there was one thing they got wrong. If the gravity reversal phenomenon was indistinguishable from a physical fall, then the people on the airship should have felt a pull in the direction of their movement.
“But reality... is a little different.”
Doloren looked around. The temperature and pressure on the deck were almost the same as on the ground. This was because Isaac was perfectly controlling the environment with magic linked to the floating stone.
“How on earth did he do it?”
Of course, Doloren knew Isaac could predict the strength of gravity through [Principia]. But there is a huge difference between ‘predicting’ and ‘manipulating’. Just because you know the precise pain of a burn doesn't mean you can freely control fire.
