Argus

If you observed Argus from outer space, you would find that this planet was like a burnt green glass ball.

The surface of this planet was in a shattered state, and a huge fissure that almost spread across the entire planet could be clearly seen even in space. And this fissure was full of fel energy that was so thick that it seemed solid. The fel energy flames triggered by this fel energy soared into the sky, setting off a firestorm more than ten thousand meters high.

There was no ocean because the fel flames had already evaporated the ocean, and even water sources were scarce. Even the small lakes and swamps left behind were all highly poisonous liquid contaminated by fel energy.

The source of all of this was the Dark Titan Sargeras, who had corrupted Argus with his fel energy.
