The World Below
Once, the World Above was full of light and life. But after the sun burst and cast the skies into flames, we were forced to flee under, into the deep and mysterious seas and caverns that make up the Underworld. The Overworld is scorching and dead now, and only the foolish live above. We are trapped, in the company of strange squid-men and spiders and living dead and massive insects large enough to make a horse seem small. Underside is strange and frightening, but it is where we must live. Alongside the dark and deep Sea of Ink, across from the eldritch cities of the cthonids, we have carved ourselves a civilization.
And, painted in blood if necessary, we will make it a home. Consider this a promise.
