A new year brings a new adventure however beginning with some increasingly worrisome questions about the new headmaster Merlinus Ambrosius whose long trek outside of time may have attracted the attention of a horrible entity known to legend as "the Gatekeeper". Determined to prove Merlin's trustworthiness James finds himself lost in a deepening web of intrigue deception and secrets that stretches all the way back to the time of the founders. With the Gatekeeper looming preparing its prophesied human host for a final reign of doom James Rose and Ralph forge unexpected allies in a last-ditch effort to stop it before it is too late.
