Maybe you could paraphrase it. You don't have to say "relics" or use their actual names, but rather, "magical artifacts" and call them something else. Void fish becomes aquatic abyssian- that sort of thing.

[When you read a lot of books you kind of end up as a walking thesaurus, and he can't help but work the problem. It's like a puzzle in a ruin- just begging to be solved.]

If it's only specific words that are erased, there's always methods of getting around that. And the story is wild enough that it would be hard to believe even if you tell the truth, so embellishing a little does no harm. Everyone loves a good story.
