Casting magic

Casting magic is an interesting feeling, Fire comes easiest, and casting it, I can feel the excitement in the magic, it flows up, and it wants to do things, it wants to have impact, it wants to warm and illuminate and burn and destroy. Tapping into it is easy enough, as the primordials I sought out taught me the fire dialect, and I remember my feelings of restlessness, of wanting to be on the move always, racing across the dunes, with the sun burning down from above. The warmth is comforting, it feels like home, the energy feels like the ability to do things, help others.
 
The next magic, surprisingly enough, is Earth, which according to the teachers, is very opposite Fire, very stubborn, very slow moving. I don't fully understand why its the next easiest for me to channel, but it is. It makes me feel the land beneath me, the sand of the dunes I have travelled so much, the land I stand on when I channel the magic. I feel that protective urge surge through me, the ability to stand there, take the brunt for the sake of others, the feeling of that care and protection, and, oddly enough, some of the time it feels like that protective desire is towards me. Which, makes no sense, I protect others, I don't get protected, why would it want to protect me?
