So, I used to be an author but I got bored and switched to Enquirer…but I have no idea what advanced professions I can take from here, or which cards I need. Help?
Enquirer doesn’t lead on to anything - it’s one of the four base professions that train your stats.
For a breakdown of which professions lead to which others, see this page of the wiki: http://fallenlondon.wikia.com/wiki/Category:Profession
In other words, it will add to your base stat of Watchful each week as long as you’re below 70. The Watchful professions start with Watcher which requires Constable connections.
Or The Great Game, iirc.
