Paradox Interactive announces Ancient Relics, a new story pack for Stellaris, the grand strategy game for Windows, Mac, and Linux PCs set in space, where no one can hear you singing show tunes. This does not have an exact release date, but they say it's coming soon. The add-on brings two new Precursors to investigate, Relic Worlds to explore, and archaeological treasures, as shown in this trailer (which sounds like its narrated by Diva Plavalaguna). Here's more on what this brings to the space table:

Uncover the ruins of long-dead civilizations in Relic Worlds to piece together the story of their rise and eventual downfall. Mine their derelict cities and ships to unearth the truth, discover powerful relics and harness them for your own empire’s ambitions.
