Clockwork horror

Clockwork horrors were metal constructs in the rough shape of a spider. They spent their time seeking out and stripping whole worlds for metal to create more of their kind, apathetic or even antipathetic to any organic life that crossed their path.

Description
All clockwork horrors look something like mechanical spiders with only four legs; the body was only some in diameter, but including the legs they were some  in diameter. On the front of the "head" was a crystal that allowed the horror to see; and two depressions on either side of this crystal acted as "ears". There were two small limbs below the "ears" that served differing uses for the different types of horrors.

The body of each clockwork horror was cast as a single piece of metal. The surface of the body was always polished and covered in pulsing, mystical runes.

History
Sages with knowledge of spelljamming theorized that the scaladar of Trobriand's design were based off of the clockwork horrors.

Notable Clockwork Horrors
Trobriand created replicas of both a copper and a silver clockwork horror.
