First seen when Parson entered the Magic Kingdom after the Battle for Gobwin Knob, he summoned the Thinkamancers to unravel the Croakamancer-Dirtamancer link up, saying they'd do it for no charge.
Isaac is a rarity among the casters of the Magic Kingdom, not content with debating and arguing over theories and hypotheses on the nature of magic and Erf, but actively working to discern reliable and consistent facts. So far, this has led to the creation of a number of devices to aid thinkamancers in better accessing nodes of amplification or attuning to the frequencies of certain G-String vibrations.
Should he ever link up with a Carnymancer, they will create devices capable of automatically switching Thinkamancers between nodes at precisely calibrated frequencies to achieve Thinkamancy that, while not as versatile, will actually rival the Arkendish in power.
