The Tomb of Black Sand

The Tomb of Black Sand (5e/OSR)

As the heavy bronze doors open outward, a gust of cold air escapes the tomb with an icy howl. The delicate sound of swishing sand and faint, ghostly whispers can be heard inside the entryway’s dark hall. Within the chilling blackness ahead lie clues to the mystery of disappearing nearby townsfolk and of this vast structure that, inexplicably, has somehow “grown” from the very earth itself.
