Create a coloring book page for adults with a focus on simplicity and boldness. Craft a scene inspired by Gothic art style depicting a group of Viking warriors on a stark and empty battlefield. Utilize thick lines to outline the figures exclusively, omitting any shading. The image will be in black and white, enhancing the coloring experience. Picture a collection of Viking warriors, each holding either a sword, shield, or axe, wandering individually across the battlefield. Convey a sense of solitude and strength as they stride through the open expanse, capturing the essence of the Viking era in this coloring page.
