The Darkling Lords encounter a city whose inhabitants are reluctant to give up their Age of Technology lifestyle. Lured by Darkstorm's promise to give them human slaves to replace the robots which used to do all the work in the city, the people infiltrate New Valarak and enslave the Spectral Knights. But the Spectral Knights find an ally in a woman who feels that freedom at the expense of others is wrong.

The story is set on the fictional planet of Prysmos, a futuristic society where all technology and complex machinery suddenly cease functioning, and its citizens are forced to rely on ancient magic to survive. This happens when the three suns of the planet align and their combined radiation emissions deactivate all technology on the planet, similar to an electromagnetic pulse effect. The titular Visionaries are knights who are split into two factions: the heroic Spectral Knights and the evil Darkling Lords. The Visionaries who wish to gain the usage of magic is invited to a competition by the wizard Merklynn. After surviving traps, dangerous creatures, and each other, survivors are rewarded with unique animal totems affixed to their armor chestplates; these talismans are based on the bearers' individual attributes while allowing them to transform into their specific creatures.
