Over the last year, we've made changes to the very early game to improve how we onboard new players, so if you last tried a long time ago, you might find that this is all you need. Remember that Fallen London isn't a run-based game like Sunless Sea – you can't really mess up and lose progress in the same way, so it's okay to muddle your way through.
But if you want more help, there's the player-maintained wiki which features various guides, and the helpful community on our Discord.
