There were several terrifying creatures in Season 1, and while Geralt will now be tasked with protecting / training Ciri in between all of his grunting and bathing, destroying monsters is still his main gig, so there’s no doubt that he’ll be doing a lot of it as Season 2 unfolds.
I guess we’ll just have to wait for Season 2 of The Witcher to find out!
The big question, though, is why this thing would leave him alive as it murders everyone in his path.
My guess is that Geralt will be narrating this opening because he’s on the hunt for whatever Big Bad (or, sure, possibly misunderstood monster) has killed up this village and taken out the Coppercloths.
