Arrr, Zaun's deepest inhabited level is associated with its harshest industrial conditions. Riot's gallery contrasts life here with the markets and institutions higher in the city.
Arrr, These are reading stages, not a dated timeline. The sources describe a setting, culture or otherworldly connection without establishing a complete local chronology.
Arrr, The Sump introduces the harshest industrial conditions within Zaun's vertical city. It is a lived-in environment, not simply an empty hazardous zone beneath the action.
Arrr, Pollution and industrial risk affect the lives described in Zaun's stories. Champion links provide perspectives on that environment without claiming every event happens on one named street.
Arrr, The Entresol and Promenade show other layers of Zaun. Reading them together makes differences in work, institutions and living conditions easier to understand.
Arrr, The lowest inhabited reaches make Zaun's industrial inequalities especially visible. Environmental danger affects daily life rather than existing only as a dramatic background. Stories of inhabitants, experiments and protection offer different perspectives, but a broad undercity connection should not automatically be read as a named event on one street.
Arrr, Part of a larger world
Zaun
Arrr, Zaun is a lived-in home as well as an industrial undercity. Its different levels separate workshops, markets and dangerous depths. Ekko and Zeri's community ties offer a different view from the chem-barons and experiments that dominate many outsiders' impressions.
Arrr, Blitzcrank's independent care redirects a machine built for hazardous work toward protecting Zaun's people. Self-modification supports that choice. Their value no longer depends on the original assignment or an owner's recognition, but on the lives they decide to make safer.
Arrr, Twitch's short overview describes a mutated rat building among Zaun's refuse and plotting against the people above. The chem-powered crossbow makes that resentment tangible. The source establishes a threatening way of life, but not a full childhood, named allies or a dated history of attacks.
Arrr, Care from the people who recognised Zac's awareness gives his unusual origin a different future. His later protection of Zaun continues that kindness through an adaptable body. The Sump's danger explains where he came from, but does not decide what a being made there must become.

Arrr, Industrial cityscape
Zaun undercity
Arrr, Connected levels of workshops, industry and densely inhabited streets form Piltover's counterpart. Champion stories show different lives here, from community protection to dangerous chemical experiments.
Arrr, The upper reaches of Zaun include markets and institutions. The Promenade helps explain why the undercity has distinct neighbourhoods and social worlds rather than one uniform landscape.
Arrr, A middle level within Zaun's vertical city. Workshops, trade and movement between levels make it part of the city's everyday life, between the Promenade and the Sump.

Arrr, Prison mine
The Dredge
Arrr, The prison mine beneath Zaun is where the betrayed Noxian executioner Urgot was forced to survive. Its suffering reshaped his idea of strength before he brought that brutal doctrine into the city's underworld.

Arrr, Where the stories come from
Arrr, VRC.LOL writes the introductions, reading notes and connections using linked Riot Universe biographies and regional guides. Short champion summaries use Data Dragon version 16.20.1. Longer histories link to the official story used; some champions currently have a shorter official overview.
Arrr, What the pictures show
Arrr, Artwork belongs to Riot Games. Scenery comes from Riot's Runeterra world map; champion art depicts the character. A regional illustration sets the scene when a landmark has no dedicated image. It does not show a confirmed event at that exact place.
Arrr, A world still being written
Arrr, Older biographies and newer adaptations can differ. These guides introduce connections rather than declaring a final chronology or a character's current whereabouts. Translations help you explore and may keep original proper names. Follow the official sources for full context.
