Thousand Hells Underworlds and Eternal City Guide

How are the Eternal City and underworlds connected?

The Steam store page describes the Eternal City as the party’s home and the underworlds as distinct destinations beneath it. A mysterious Ambassador provides changing contracts, and the route taken through an underworld can change how the story plays out. A complete map is not public.

The encounter types page records the challenges found along a route, while routes and conditions tracks route hypotheses.

Does every run use the same underworld route?

The store description says the game can create a new unique quest or let players retry a failed mission, and that each hell is distinct. This supports replayable variation, but it does not establish a fixed order, random seed rule, or universal route branch.

Record the quest, destination, entry choice, encounters, and exit result in the route testing log.

Which underworld facts are still unknown?

The complete destination list, travel requirements, route locks, and relationship between underworld state and endings remain unconfirmed. Do not publish a map or guaranteed route until the release build provides repeatable evidence.
