Cybertron has been invaded. The Transformers encounter unwelcome guests at the heart of their planet--and they may not have their hosts' best interests at heart.

Refugees from another world, the Visionaries' startling magical abilities could make them powerful allies... or dangerous enemies. It turns out there are some of each. When Virulina, leader of the Darkling Lords, discovers that the Transformers are vulnerable to magic, she uses that weakness to try and gain control of Cybertron! Leoric of the Spectral Knight teams up with Ironhide to stop her, but they quickly find themselves facing not just the Lords, but all of New Prysmos itself.
