Rasmus narrowed his eyes because of the sand that kept entering his eyes. He couldn't see anything but a vast desert as soon as he left the city's port, and the two suns made it worse. Fortunately, he managed to learn about manipulating nature after he grasped the principle of it. He could manipulate the heat in the air and get rid of it before it could touch his skin.
He no longer suffered under the sun's heat. Instead, he willed the warmth away, stripping it from the air before it could touch his skin. It wasn't magic in the traditional sense, no formations, no incantations. It was something more profound.
Mana itself could understand him. That was the revelation. As long as his comprehension of nature aligned with Mana's inherent logic, it would listen to him.
