A shadowy club owner summons Elvis for aid, and a voice he knows delivers a cryptic warning: a door exists that cannot be shut, and the means to keep it eternally ajar.

Elvis, Keta, and Nancy journey into the realm of the dead, their purpose to locate Ventura and return him to the living world. Meanwhile, in a distant place, an elder Mayakén reveals unsettling abilities.

A presence stalks the land, undeniably malevolent. Yet the means of its destruction remain elusive, and a deeper mystery clings to its victims: their bones are unnaturally dark, like polished obsidian.

With Lupe’s assistance, the crew constructs a snare to capture the beast, drawing upon the dwindling resources of the Last Days Division. Yet, while they prepare, Death’s attention is fixed on Elvis.

Fleeting glimpses of earlier days surfaced, painting a portrait of Mayakén's past and illuminating the peculiar nature of his upbringing.

As the opportunity to safeguard the gateway dwindled, Elvis and his companions united to breach the Conclave's defenses—a desperate bid to liberate Mayakén.
