Ding ding ding, Sans is absolutely right: magicians in Lambert's world have labs, and it turns out sorcerors and sorceresses really happen to like experimenting on shit (and some are straight up crazy) so guessing what you find in places like that tends to be the sort of game with the worst prizes. You'll never guess what sorceress X came up with that could kill you!

"Yeah," is what Lambert says out loud. "Mostly for alchemy, but it depends. We had one for making potions at Kaer Morhen, but it used to be where mages made witchers in the first place."

He'll walk where Sans leads, a little less sway in his step. His eyes dilate, adjusting to their darker surroundings. Having that low-light vision is a handy thing.
