Ignis Fatuus

Ignis Fatuus was a clone of Eidolon created by Echidna. He shared his powers and memories, but, like all Echidna clones, felt a driving desire to destroy everything his original cared about. He was only named in the chapter tags.

The clone displayed a "flickering" ability much like Gray Boy's, which he used to conjure costumes for himself and a clone of Alexandria, as well as to heal injuries.

Trivia

The term ignis fatuus means a will-o-the-wisp - a malevolent ghost that leads travelers astray - or more generally something that misleads or deludes; whereas "Eidolon" means an idealized image or phantom of a person.
Had Wildbow not received more donations, Ignis Fatuus would have had a larger role in the story, serving as a catalyst for Skitter investigating the settings lore earlier then she did in the cannon story-line. Consequently Worm would have been far shorter.<ref>Comment by Wildbow on Spacebattles</ref>
