Aetna
Aetna could represent many things.
A modern version of Hephaestus’ automatons, metal people (& animals) he crafted were as real as living beings. This could mean a “Lars and the Real Girl” romantic or friendship equivalent for Hephaestus, who seems alone.
Mount Etna is often associated with Hephaestus. It is said to imprison the monstrous Typhoeus, who also arbitrated a land squabble between Hephaestus and Demeter.
The eyes on screens could be a nod to the many cyclops who worked for Hephaestus in the myths. Eyes also symbolize perception and vigilance, access to forbidden knowledge, and surveillance.
