Create me an image with a dark and gloomy tone, with an army of World of Warcraft-style warriors, carrying weapons such as swords, axes, bows, crossbows, and staffs of ice and fire magic. There should be dragons in the sky representing the warriors, with flames coming out all over the place with red and yellow colors, keeping the gloomy style. The image must have the following text "Umbra Draconum", the text cannot be omitted.
