Abednego's Ashes

In an irradiated post-apocalyptic world, a small community of humans survive by making forays to farm in nearby parallel dimensions. Unknown to them, their actions draw the attention and ire of ancient races that govern access to the dimensions. With help from secretive mythical beings and the courage of an unobtrusive leader they must find a way to survive the wrath of the demon hordes sent to “cleanse” the worlds they have infested.
