KL-2

K-12 is a dead star. The system includes an asteroid field and at least one barren planet.

The Moebius Foundation visited the dead planet in order to investigate a xel'naga site there. They released an entity, which called itself the "Voice in the Darkness" and other names.

It was seemingly defeated by the band of Dark Templar which arrived to investigate, but it managed to hide itself from protoss scans.
