Romance is set in the year-or-so after the end of S3, so kinda canon-era. Actually, I should probably make sure I finish it befor s4 starts, lest I totally abandon it when canon josses it!

Arcane Asylum was great, but it was also focussed very closely throughout on Arthur and Merlin, which is the hook to keep the reader there. Epic Romance is mostly from Gwaine's POV while he's in a diff kingdom from those two *g*

But, I'm probably mostly just paranoid!
