The Tywon are relatively close to Earth and are able to listen to old school radio and TV transmissions from a few hundred years ago.

It could be similarly be possible to listen to old school radio transmissions that are thousands of years old from now-extinct species that encountered the Scryve provided you go far enough from the source in space.  The Tywon device which listens to Earth transmission could be used to scan these old transmissions looking for certain key words.    Knowing where the transmission came from could help date the signals (although sometimes they can bounce back and forth).  The crew could also listen to those transmissions when on break maybe watch alien sports interrupted by urgent news.  The various beacons found in this game could be used to gather intel (old and new) as could the Starbases we visit.  This way, when we visit a starbase, we could see Ancient/recent news.  The recent news would be from subspace transmissions of nearby races, the ancient news from the old school radio/tv transmisions.

In order to get keywords in the languages from now extinct races, our allies could provide some words and the rest could be provided by libraries in ruins and/or a lexicon/Rosetta stone type of document kept by the Measured.   These transmissions, now recorded could be used to counter the sanitized version of history by the Scryve.   Name of extinct races could be part of the words that are searched for automatically in these old radio/tv transmissions.

Anyhow, it's one use of that tech I'd make if I were in the situation presented by the game.
