I'd think super-advanced stasis tech. Or maybe it's not "stasis" at all, and that's just a buzzword used in the art book.

What if the Protheans created a machine that stored Prothean DNA patterns, and was capable of using those to artificially create a new Prothean only a few decades before the present day? We know Prothean machines are at least durable enough to survive 50,000 years reasonably intact.
