Epsilon started drawing on a paper that he self-conjured along with a magical pen. He was designing the drone shape and added details such as weight, height and width. After about an hour, he decided on the drone shape.
The drone would be cone-shaped with a tip that was thinner than a needle. Its height would be about 1.5 meters and the length would be around 2 meters. It was large enough for a small-built human to fit inside it. Its weight should not be more than 100-150 KG.
As the design finished in Epsilon’s mind, he started controlling his magical energy to set up the machine. Three hours later, a drone was lying on the ground. Right now, it was nothing more than a metallic cone with a needle tip giving it a sharp exterior on top.
He did not add anything to it as yet. He opened it and commented while looking inside the drone.
“It’s now time to fit it with the technological parts.”
He took a deep breath and used the gravity knowledge of the Werfur race and then added his knowledge of Gravity, creating a sphere-shaped metal gadget that will work inside the drone. This would allow it to defy the principles of gravity. He also added a piece of spell and technology using energy knowledge to let the gravity core use electricity to perform gravitational pull.
Without this piece of spell or technology, the gravity core would not have needed energy to start working. If he did not add this, the drones would be completely dependant on Epsilon’s magical energy.
With the way it was designed at the moment, all of them would still use Epsilon’s magical energy but every time they used the gravity core, it would be completely like putting a spell in action. So, if Epsilon used the Gravity Spell to do something and expend magical energy, the drones too would use magical energy like him to use the gravity core.
He would also add some quotes on gravity so that the created gadget would be more powerful and would consume less energy while performing gravitational work.
‘Gravity Core – Epsilon Brand’
‘Gravity (from Latin gravitas ‘weight’ or gravitation, was a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light were attracted to (or gravitate towards) one another. On Earth, gravity gave weight to physical objects, and the Moon’s gravity caused the tides of the oceans. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing and forming stars and caused the stars to group together into galaxies, so gravity was responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become weaker as objects get further away.’
‘Werfur – Gravity Knowledge’
‘In general relativity, the effects of gravitation were ascribed to spacetime curvature instead of a force. The starting point for general relativity was the equivalence principle, which equated free fall with inertial motion and described free-falling inertial objects as being accelerated relative to non-inertial observers on the ground.’
‘In Newtonian physics, however, no such acceleration could occur unless at least one of the objects was being operated on by a force.’
‘Knowledge – Energy Use – Transmutation’
‘Electrical energy was energy derived as a result of the movement of electrons. When used loosely, electrical energy referred to the energy that has been converted from electric potential energy. This energy was supplied by the combination of electric current and electric potential that was delivered by an electrical circuit (e.g., provided by an electric power utility).’
At the point that this electric potential energy has been converted to another type of energy, it ceased to be electric potential energy. Thus, all electrical energy was potential energy before it was delivered to the end-user. Once converted from potential energy, electrical energy can always be called another type of energy (heat, light, motion, etc.).
‘Knowledge – Potential Energy’
‘In physics, potential energy was the energy held by an object because of its position relative to other objects, stressed within itself, its electric charge, or other factors. Common types of potential energy included the gravitational potential energy of an object that depended on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) was the joule, which has the symbol J.’
‘Fantasia – Quotes’
‘Sometimes I think gravity may be death in disguise. Other times, I think gravity is love, which is why love’s only demand is that we fall.’
‘I would feel infinitely more comfortable in your presence if you would agree to treat gravity as a law, rather than one of a number of suggested options.’
‘Pick a flower on Earth and you move the farthest star.’
After everything was completed, Epsilon commanded.
With his words, the Gravity Core started levitating in the air. Right now it still used Epsilon’s energy.
Epsilon purposely did not sell 50 city-level energy that was saved up in his batteries. He produced a black battery and added it inside the Gravity Core. The black battery was filled with one-city level energy and would be connected to every part of the drone he created. He added it to the Gravity Core, as he was going to put the Gravity Core at the center of the drone.
As he added the core, he used his magical energy to connect the Gravity Core and the drone to each other. For simple matters like connecting like this, he did not need to create any other electrical or magical parts; he could do it using basic spells.
After the connection was completed, he whispered.
Seconds after, the Gravity Core started shining with white energy, consuming electrical energy inside the battery and the cone-shaped drone picked up from the ground.
Epsilon had managed to create a drone capable of flight without using any conventional means; in fact, it used gravity to fly like a magnet flying in the air.
