During the prologue of major events to happen later in Reverse: 1999, a short monologue occurs, pertaining to the "Storm". It is narrated by Vertin. The screen once more fades to black, and we are introduced to the deuteragonists Regulus and APPLe. Furthermore, they had tied up Foundation Investigators, who had been stalking Regulus for days. Simultaneously, her ship, also dubbed APPLe, would be bombarded by a vessel from Manus Vindictae, a "terrorist group" before having to abandon ship and return to the shore.

King's Trail
The expedition introduces the deuteragonist Sonetto, as well as finally introducing Vertin (addressed by her alias, Timekeeper). Vertin was fell into a coma due to a rushed ritual summoning her at Battersea Park. Currently they were located across the river from Chelsea (City in London), Regulus, and APPLe, as Sonetto briefs her of what had transpired. It is also revealed that Vertin had not trained herself to battle with arcanum, whilst also revealing they had been classmates before. They use a floppy disk, given by Madam Z, to teleport themselves across the other side of the river to subdue Manus Vindictae.

Teleport
It is revealed to Regulus that Sonetto, the Investigators, as well as the Timekeeper, are all part of the St. Pavlov Foundation. It is also stated that Arcanists require licenses in order to use arcanum; Regulus is asked to register for such license. But, an ambush would transpire, as Regulus and APPLe would teleport away to Kingly Court. The team would split up, as Regulus and Sonetto would depart to Kingly Court to find Regulus. It is also stated that Vertin has their own mission transpiring there.
