Summer of 1908

Summer of 1908 is the date of the renegade peculiars’ disastrous immortality experiment in the Siberian tundra. Intended to reverse aging and free its participants from death’s limits, the undertaking instead produced the Hollowgasts, making the season a turning point in the history of peculiar society and a warning about the consequences of trying to master time.

The ambition behind the experiment

Peculiars remain mortal, and time loops delay aging only at a price: long-term residents are separated from the ongoing present and can enter it only briefly without suffering harm. Around the turn of the twentieth century, a splinter faction sought to overturn those limits. Its members wanted not merely suspended aging but its reversal, imagining eternal youth beyond the loops and unrestricted movement between past and future.

The faction treated loop mechanics as a possible route to power over both time and death. Miss Peregrine regarded the proposal as incompatible with the laws governing the world and warned that its adherents were effectively trying to make themselves gods. Their project therefore set the established practice of using loops for protection and continued life against an attempt to appropriate time itself for immortality.

Participants and departure

Miss Peregrine’s two brothers, described as technically brilliant but lacking sound judgment, embraced the proposal and asked her to help realize it. She refused, warning that it could not and should not be done. They were familiar with the art of the Ymbrynes because they had grown up among trainees at Miss Avocet’s academy; Miss Peregrine considered that partial knowledge dangerous rather than sufficient.

Despite warnings and threats from the Council, the brothers joined several hundred members of the renegade faction, including powerful Ymbrynes. In Summer of 1908, they entered a nameless loop in the Siberian tundra, a site that had gone unused for centuries. Their companions expected the group to return within a week, chastened by the experiment’s failure. Instead, the expedition ended in a catastrophic explosion.

The explosion and the first Hollowgasts

The blast was powerful enough to rattle windows as far away as the Azores. At first, those who knew of the expedition assumed that everyone involved had died. The explosion, however, was not the end of the participants: weeks later, attacks on peculiars began, carried out by creatures visible only to peculiars such as Jacob Portman.

It took time to identify the attackers as the experimenters themselves, who had survived in a radically altered state. The transformation inverted the faction’s hoped-for ascent: rather than becoming immortal masters of time, its members became Hollowgasts. One proposed explanation is that the experiment reversed their aging so far that they returned to a state before their souls had been conceived, leaving them without hearts or souls. Their immortality was therefore real only in the bleakest sense: it meant a prolonged existence marked by suffering, isolation, and hunger for peculiar blood.

Consequences and significance

The failed experiment created a new and persistent danger to peculiars. Hollowgasts preyed on them in hopes of finding salvation through their blood, and a Hollowgast that consumed enough peculiars could become a Wight. The transformation thus carried consequences beyond the Siberian site, turning a faction’s private bid for eternal youth into a threat to the wider community.

The episode also clarifies the limits of time-loop life. Loops can shelter peculiar people and delay aging, but they do not abolish mortality; the experimenters’ fate instead shows how a supposed escape from death can become a more punishing form of existence. Summer of 1908 is remembered not as the beginning of a new mastery but as the origin of the Hollowgasts and the catastrophic cost of treating the laws of time as obstacles to conquer.
