Carved from large blocks of obsidian, this four-sided column gradually tapers as it rises and terminates into a pointy pyramid at the top. The structure appears to be completely solid and stretches at least twenty-five feet into the sky. There is not a mark on the obelisk, and its surface has been polished to a gleam.
The Obsidian obelisk is the heart stone set at the center of Androctonus' main cross roads were the community can gather peruse the wares of the street vendors, share a communal meal during one of the cultural high festivals, allow the young of the city play in security near where they were tended in the hatcheries.
