Once in Scotland Zachary reunites with his childhood friend True MacDonald and his sister Brandy, with whom Zachary is immediately smitten. Hoping to find giant squid, the expedition instead resulted in the loss of an expensive submersible and its pilot after they are attacked by an unseen creature Zachary identifies as the source of the mysterious phenomenon " The Bloop". Zachary is also dealing with the impact of a disastrous expedition into the Sargasso Sea, which has left him with PTSD and afraid of the water. Hundreds of years later Scottish-born Zachary Wallace has returned to Loch Ness to reconnect with his father Angus, who has been accused of murdering wealthy land developer Johnny Cialino over money owed. In the resulting chaos the monsters kill all but one of them, Wallace's cousin and protagonist Zachary Wallace's ancestor, who swears to protect the relic. Believing the monsters are the spawn of Satan and using them makes them complicit, the Knights rename themselves the Black Knights. Each year the Knights will raise and lower a gate that allows several adult monsters to enter but not leave. They are aware that monsters use the cavern as a path to the ocean, so they deliberately block their path so they can serve as guardians. Shortly after the death of William Wallace, a group of Knight Templars bring his heart to Loch Ness with the intent to hide it in a cavern.
