The Core of the Matter

"The Core of the Matter" is a cross-faction mission in the Star Trek Online video game. It is the third mission of the "Yesterday's War" episode.

Description[]

Mission text: <Rank>. We've detected significant temporal activity in the Galorndon Core system, circa the 23rd century. I'm going to investigate it, and I'd like you to join me.; We believe the Na'kuhl are involved, along with a planet-killer... a Doomsday Machine. If so, we need to stop them at all costs.; I'll provide your ship with holographic camouflage - it's best if the Romulans of that time don't see a vessel from the future.
