Estinien thinks about that and then nods. The terminology for that sort of thing has gotten complicated, as of late, but Geralt's distinction does seem relevant enough to acknowledge.

"Aye. Not in the grand scheme of things, it would seem. We never had cause to consider the idea of traversing to entirely new universes before ending up here. The shards were surprising enough on their own."

He pauses for a moment, and then adds:

"I've sometimes wondered if our worlds are meant to be the shards of the Singularity's whole. 'Twould fit with the Abraxian's conception of it, at least."

As annoying as it is to think about the Source being a shard of an even greater Source. It's all a bit much, really.
