create me a simple banner in the style of сетинг — Київська Русь XII–XIII ст., без магії та фентезі; and add the attached 3 charatcers. Do not change the characters in any way .. make the background to be in a historical colors..maybe gradients of brown and maybe add fire ..something simple. Do not draw anythibg..the banner should be one tone color or gradient but no images.. just add the 3 characters and do not draw anything extra
