I am a decent way into the Witcher 3, having just completed most of the Bloody Baron's questline to find his wife, save for going back to the Bog to try and rescue here. I'm hoping to avoid any major spoilers of this game, but anything from the previous two is fine, since I haven't played them anyway and have no intention of doing so.
Every once and a while, when a storm rolls in, Geralt makes an almost angry remark:
Damn, a storm is coming in.
Does Geralt just hate storms as anyone might, or is there a specific lore-based reason as to why?
