Third image actually comes from a Falcom official artist (the one who also did the Schera-and-Olivier-in-a-bar-drinking wallpaper).

Check these useful LPs for FC and SC, though I'd advise you skim the FC LP since it's based on the old PSP version with a worse translation and edit job vs. PC.
Is there a comprehensive summary/synopsis of FC and SC available anywhere? Been a while since I've played them and my memory's fuzzy on a lot of the plot aspects. Same for CS...
