Role of bold, italicized phrase in the above sentence?
I think it's an appositive-- noun phrase that clarifies or describes a noun-- for it's clarifying the subject of the clause "no one", emphasizing, using the adverb phrase "not even", that "not even noun phrase X".
I question the placing of the noun phrase at the end. Shouldn't it be next to the noun it describes or clarifies?
I wouldn't call it an absolute phrase because the noun phrase isn't modifying the entire sentence.
