I had the exact same thought when I saw this, there are a ton of references to Berserk in dark souls. I just started (and finished) reading it this month.
The last time I saw an eclipse (solar, lunar, doesn't matter) was never. I still have yet to figure out why I'm so unlucky, with both not being in the zone of sight AND not being there at the right time.
I live in Morocco btw, which kinda explains my point.
