Necron stairs

thingiverse

Staircases rise up from the dark, ancient earth like colossal sentinels, their rugged facades weathered to a deep, foreboding grey. Inspired by the towering basalt pillars that pierce the skies in eerie silence, these stairways evoke an otherworldly presence, as if they've stood watch for millennia over the forgotten realms of the Necron hordes.
