[ Not a mass grave. The reality is, an abandoned mass grave would not have brought Geralt here. He might've examined it, followed any trail left behind briefly just in case, but it'd have been nothing in particular to note. Place like that, practically no man's land, it only makes sense that's where the bodies would go. And this area has a long history of war and conflict.

This is different. Something else. ]

No. [ Sam will recognize the significance of that. There are few bones Geralt cannot recognize. He'd at least be able to tell if it belonged in the desert: a reptile, an arthropod, a canine. These don't appear to. And the bones are not old enough that they could be considered fossilized, from some ancient past. ] These metal plates, they've been attached to all of them.

[ They've been tinkered on, in other words. Then discarded. Something failed? Perhaps. If this were all he found, if the assorted pile of desiccated limbs were all, that would be one thing. It isn't. ]

There's more. A door, buried under a cave-in. Something's behind it. I can smell it.
