Quick answers

FAQ

Is 'Seance' spelled with a cedilla?

Steam achievement display uses Seance without a cedilla in the community board scrape we verified. In-game UI may stylize the word differently, so search both forms if a filter tool is being pedantic about spelling.

What does moniker mean here?

A short animal nickname printed for photo-card matching, such as Lark or Badger. It is not necessarily spoken in dialogue as a title, and it never replaces the notebook step that locks a real name to a machine ID.
