Morgoth appeared as a vast, towering tyrant, permanently locked into a dark, physical form. He was clad in black armour, held a massive, unblazoned black shield, and wielded Grond, the heavy Hammer of the Underworld. He wore a great iron crown that held the three burning Silmarils.
Fingolfin, the High King of the Noldor, shone like a star amidst the darkness. He wore mail overlaid with silver and carried a blue shield set with crystals. He wielded the sword Ringil, which shone with a cold, pale light and glittered like ice.
Following the duel, Morgoth’s physical appearance was permanently altered. He bore seven unhealing scars from Fingolfin’s sword strikes. With his final blow, Fingolfin hewed Morgoth's foot with Ringil, leaving the Dark Lord permanently lame and walking with a limp for the remainder of his existence.
Finally, as Thorondor, King of Eagles, swooped down to rescue Fingolfin's body, he marred Morgoth's face with his talons, leaving permanent scars upon the Dark Lord's visage.
