Trope-a-Day: In Working Order
In Working Order: Usually averted (except in cases where the artifacts include what are, functionally, people), despite Ragnarok Proofing – most elder-race artifacts are found after time periods adequate for even vigorous Ragnarok Proofing to have been overtaken by entropy, or overwhelmed by whatever was responsible for said species not being around any more, and the majority of them require considerable patching up or reverse-engineering in order to work at all – or at least as expected.
Data storage devices are, as might be expected, the most common aversion of this aversion – but then, that comes with its own dangers.
