The Spire are coming...

Ravaged by their recent encounters with the same AIs that pushed humanity to the brink of extinction, the Spire are an alien race that have also been all but destroyed. However, while the AIs were successful in their surprise attack against the Spire, the Spire are far more powerful than even the AIs seem to have realized. The Zenith were broken-down and ancient when humanity encountered them, but the Spire were at the height of their deadly power until quite recently.

Now the splintered remains of their race are regrouping, and entering the galaxy with a vengeance. Their attitude toward humanity, who spawned the AIs that harmed the Spire, is unclear. Proceed with caution.
