The Darkening Wild
Morgoth, once known as Melkor, was the first Enemy who fought against the Ainur and came to Middle-Earth ahead of them, founding a vast fortress in the frozen north. For thousands of years he brought war, strife and misery to the world, until he was finally vanquished in the Elder Days.
Morgoth is the one who created the Goblins and Orcs, Trolls, and even Dragons during the wars of the First Age. He brought the Balrogs to his side and used them as generals in his armies. He ruled from the Hells of Iron, and worn an Iron Crown.
