Epic Movie Poster for 'Lord of the Rings: Wrath of the North'

Create a dramatic and epic movie poster for Lord of the Rings: Wrath of the North. The scene should capture a dark, intense atmosphere, showcasing the northern stronghold of Erebor (the Lonely Mountain) in the background, partially shrouded in mist and snow. In the foreground, feature a massive battle scene with armies of dwarves, elves, and men united, wielding swords, shields, and bows, standing firm against a horde of dark goblins, trolls, and fire-breathing dragons. At the center, a mighty and imposing dragon, Drogoth, with fiery red scales and glowing eyes, soars above, casting a shadow over the battlefield. Surrounding him, smaller fire drakes circle, adding a sense of chaos and destruction. Position the main characters—Dáin Ironfoot, an armored dwarf king with a fierce and determined expression, a powerful elven leader resembling Galadriel with a serene yet intense look, and a human warrior leader, symbolizing unity—at the forefront, ready to charge into battle.
