The Hiss

Lore & Background

The city of Trench is defined by its walls and by the nine bishops who sit at the apex of Vialism's hierarchy. Each bishop carries a name that feels deliberately abstract, almost phonetic, as though the word itself has been stripped of ordinary meaning and repurposed as a title of authority. Hiss occupies one of those nine seats, and in the visual and narrative language of the Trench era, the bishops are presented as a unified front—robed, masked or veiled, speaking in concert rather than as individuals. Their power is not shown as brute force but as an inescapable ambient control: the citizens of Trench do not so much fear a single tyrant as they fear the entire structure.

The lore surrounding the bishops was layered in gradually. The Clandestine singles released ahead of the Trench album each spotlighted a different facet of Vialism's machinery, and the vialism.com microsite allowed fans to piece together the hierarchy, the rituals, and the geography of the walled city. Hiss, like the other eight, is a node in that web—a name you encounter in a list, a figure you see in a wide shot of the bishops arrayed together, a voice in the chorus of decrees that the citizens of Trench must obey. The narrative tension of the era comes from the band's alter-ego figures positioned outside those walls, looking in, and the fan community's collective effort to decode what each bishop's name, symbolism, and role might signify within the larger allegory.

What makes Hiss resonate with the fanbase is the way the name itself evokes the sound of suppressed noise, of a warning that has been strangled into a whisper. In a city where the bishops' word is law and individuality is erased, the very act of naming a bishop with a word that sounds like a stifled exhalation carries an almost ironic weight. It is a detail small enough to be overlooked in a single listen but rich enough to reward the fans who return to the lore again and again, searching for the threads that connect one bishop to the next.

In Their Own Story

The bells had not rung in three days. In Trench, that meant the bishops were still. Citizens pressed their ears to the cold stone of the outer wall, listening for the low harmonic that always preceded a decree. A child tugged her mother's sleeve and whispered, 'Is it Hiss this time?' The mother did not answer. You were not supposed to name them. You were supposed to hear the name and feel it settle into your chest like a second heartbeat, one that beat in time with the others, all nine, all at once. Above the wall, in the grey light that never quite turned to gold, the robed figures stood in their fixed positions. Hiss did not turn. Hiss did not need to turn. The silence was the message, and the message was: you will wait, you will listen, you will not speak until the nine have finished speaking for you. The child pressed her palm flat against the stone and felt, or imagined she felt, a faint vibration. A hum. A hiss, barely there, threading through the rock like a wire carrying a current no one was meant to touch.

Reader's Guide

The Hiss figure belongs to the broader Trench narrative thread that Twenty One Pilots constructed around their 2018 Trench album and its supporting media. The lore was seeded through the Clandestine singles, each of which introduced or deepened a different layer of the Vialism hierarchy, the geography of the walled city, and the nine bishops who govern it. The vialism.com microsite served as an interactive puzzle for fans, presenting fragments of text, imagery, and structure that could be assembled into a coherent picture of the city's political and spiritual architecture.

The bishops, including Hiss, were not presented as individual characters with backstories in the traditional sense. Instead, they function as a collective symbol of institutional authority, and their individual names and positions were revealed piecemeal across the singles, the album's track listing, and the website's hidden content. This deliberate fragmentation was a core part of the fan experience: the community collectively decoded the lore, cross-referencing clues, theorizing about what each bishop's name might signify, and building an unofficial mythology that the band never fully spelled out.

The Trench era matters to the band's overall story because it represents the most elaborate narrative world they have constructed, a multi-media allegory about control, conformity, and the struggle to maintain individuality within an oppressive system. For the fan community, the Hiss and the other bishops became touchstones for that allegory, names that carried weight beyond a single album and into the shared vocabulary of the fandom. The lore's strength lies in its openness: it provides enough structure to be decipherable but leaves enough ambiguity that every fan's interpretation adds a new layer.
