So, I can see a group of adventurers that includes a soldier in camo, a cowboy or mountie or NY cop with a horse standing by a centaur holding a rifle with his other arm around the skittish horse to calm it. There might be one or two more humans in modern hiking clothes and a talking, clothed racoon or two and a 'normal' dog or cat. A tinkerbell pixie or a kami or a Slarg. If you were able to adventure with creatures out of myth and legend, who would you want at your back?
They are standing on a street that is cleanly sheared away a few feet in front of them. Behind them you see a drug store that has one wall and a corner of it's sign neatly cut off. The window has been broken and the door jimmied. Maybe you see a telephone pole or enough else to tell that this is a displaced small town. In front of them is landscape from elsewhere, or maybe two or three elsewheres. An OZ type alien city in the distance. A gas station from the '50s -- but off somehow. A tessaract in a sky that is itself patchworky. Stonehenge. But the characters are looking at the flying dragon. That is heading in their direction and doesn't look friendly.
Richard likes this as a cover idea. But it is WAY beyond my artistic skills. He plans to sketch a rough, but is way behind due to bad flu. So, if you are interested, have at it.
Maybe add an elf or two?
