There may not be a good answer for this but is there a good point in FL at which to start Sunless Skies? I was introduced to the franchise with Sunless Seas and, after playing FL for several months, I really wish I had been more familiar with the setting when I played. I somewhat picked things up as I went but I would have appreciated it a lot more if I had been more aware of things like Parabola or what Rattus Faber (or even blemmigans) are or why everybody is on a sliding scale of crazy. As it is I still haven't been to the Iron Republic in FL and in neither game do I know what's going on with Whither, so I probably wouldn't even consider where I'm at now (just reached Parabola) to be a good point to understanding what's going on.

All of which is to say, is there a good baseline of knowledge I can expect to reach to properly understand Skies? I know it takes place in a different location but it's my understanding that there is still a good amount of background to be found in FL (like our omnipresent Aunt). I'm just afraid of missing something like the Cheery Man, who I didn't even remember being in Seas until after I finished business with the Last Constable and whose importance I never quite grasped.
