Create me an image in horizontal format that will be used as a cover for a video

Create me an image in horizontal format that will be used as a cover for a video game guild. The image should have a somber and dark tone, with flames rising from the ground in shades of yellow and red, keeping that dark tone. From far behind should emerge the shadow of an oriental dragon. From the floor should anchor a banner, with a dark yellow flag and a line in the middle of dark red v-shaped, and in the center place the logo of a full oriental dragon in black. Finally before the flames that appear 8 warriors in the style of World of Warcraft or Albion Online, wearing clothes in dark tones and weapons such as axes, swords, mage staffs of ice and fire, spears, and sticks. And finally below the image the following text "Welcome to Umbra Draconum". Centered text, first smaller the "Welcome to" and underneath bigger and more imposing the text "Umbra Draconum".
