Erecting the Monolith

I gathered four black dominoes from the shadows beneath the sofa. Their polished resin bodies bore cryptic white indentations, resembling ancient tallies. Kneeling upon the woven rug, I aligned three slabs flat upon the floor to form a foundation, then hoisted the final tile upright. It wavered precariously under my fingertips before finding true equilibrium. I withdrew my hands, stepping back into the dimness to admire the lone black pillar standing resolute against the expanse of the room.
