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, in the middle of the flag should be a thick v-shaped line extending from side to side and serve as a background, and in the center should be a black logo of an oriental dragon. Finally, before the flames there should be 8 warriors in the style of World of Warcraft or Albion Online, wearing dark clothes and weapons such as axes, swords, ice and fire mage staffs, spears, and staffs. 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".
