Assuming role of counter-arguer. Initially the artifact undeniably smells of Reaper, but some things don't really match what else we know about them and their methods. The "cables" are chains which were used to drag the artifact there, not really the kind of wires seen in ME3, I think. The object directly emits some immense energy that transforms its victims, which isn't really like anything we've seen from Reapers before. Same goes for the language thing; to my knowledge there aren't any other instances of Reaperish or any other alien language being acquired or used this way. (Prothean doesn't count because it requires the Cipher.) Blue colour perhaps indicative of Reaper tech, though hardly proof.

What is difficult to refute is the opening scene in #2 where some unknown speaker says a bunch of really Reapery stuff, presumably in Harper's dream.
