The named cast of The Piper of Dawn centres on six heroines: Elisabeth Liebig, Helena Wolfen, Gretel, Jimo Li, Hypnos, and the Sissi / Nene / Aurora Ludwig trio, alongside forty or more named NPCs in Diamond City. They are not decoration: the relationships run through the six-faction reputation system, so who you spend loops with changes which ending you reach, not only what dialogue you see.

The six central heroines

The store description for AppID 3804370 names the central six.

  • Elisabeth Liebig
  • Helena Wolfen
  • Gretel
  • Jimo Li
  • Hypnos
  • Sissi / Nene / Aurora Ludwig — listed as one entry under three names

That is the full roster the developer has published. Their roles, factions, and individual storylines are not detailed on the store page as of 2026-09-25, so this site names them and does not assign them to a faction it cannot source.

The wider named cast

Behind the six, the store description counts forty or more named NPCs in Diamond City. That is a large crowd for a game tagged Singleplayer, and it lines up with the Factions and Multiple Endings tags: a city this populated exists to be routed through rather than cleared.

Individual names beyond the six heroines are not published, so the count is recorded here without inventing a roster to fill it.

How companions feed the endings

Companions sit on top of the faction system rather than beside it. The factions page covers the six reputation tracks; relationships with the named cast are how those tracks move. That is what makes the choice of who to spend a loop with a strategic decision instead of a preference.

The Multiple Endings and Choices Matter tags on the store page are the confirmation that this branching exists. Which companion leads to which ending is not published, and the endings page records that boundary rather than filling it in.

What is not published about the cast

As of 2026-09-25 the Steam store page confirms the six central heroines by name, the forty-plus NPC count, and the existence of faction and ending branches. It does not publish:

  • which faction each heroine belongs to;
  • companion dialogue, affinity values, or romance routes;
  • the NPC roster beyond the six;
  • any companion-to-ending mapping.

Those are the parts a reader is most likely to come here for, so they are named as gaps instead of being filled with plausible-sounding guesses.

Save and Load are framed as two favourite gods, and Oracle blessings from Ancient and Outer Gods stack across loops, while reputation and choices across cycles decide which ending plays out.
