[ Oh dear you just had to ask Helios that didn't you Sasuke. ]

Ah! W-Well it depends on the world and the m-magic in question really. Elemental magic uses the four basic elements. Earth, fire, wind, water. Typically it takes more energy to form something like a ball of water or fire when the specific elements aren't readily in the vicinity. But! It's still possible. Illusion magic is another story entirely. You can basically bend the light around you t-to form an illusion of sorts. [ And Helios will demonstrate of course. His eyes will glow bright green then and in front of the two of them in the palm of his hand will form a bright, red, apple.

He smiles as he closes his hand around it and it disappears in an instant. ] Like that!
