Galaxy's End

Dax, Captain of the Kyrie, has been flying in space for long enough to know his way around interplanetary travel. Maneuvering, gravity wells, wormholes to get you between solar systems; he’s old hat at it all.

But the most important part of any space journey is constant connection to the Tactum. 

The Tactum is the subspace communication link between a thousand worlds. Five hundred years ago, it joined one solar system to another, enabling instantaneous communication for all citizens of the galactic government. The Tactum enabled humankind to colonize the galaxy.

And it has never gone silent. Until right now.
