Create me an image with a somber, dark tone for a guild cover

Create me an image with a somber, dark tone for a guild cover. 1. Place at the bottom of 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". 2. Place 7 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, bows and rods. 3. From the floor must anchor a banner, with a dark yellow flag and a dark red v-shaped line in the middle, and in the center place a full black dragon logo. 4. Place in the background flames rising from the ground in shades of yellow and red, keeping that dark tone. 5. From the bottom of everything should emerge the shadow of an oriental dragon.
