Chapters 101–125 Vol. 2 Read

Ch. 101Theus and Theus and Theus

Theus tested how his soul and abilities interacted with different vessels on the Golden Throne, concluding that dead vessels could still be controlled while the white-robed priest’s vessel resisted his descent. As he prepared to investigate Monica’s summoned souls, he realized he could still activate Mind Link and wondered whether Throne Theus had a Symbiotic Pact of his own.

  • Theus found that the Symbiotic Pact’s abilities could not be used through his other vessels, and Mind Link received no replies.
