The Lucifer system was named after its tragic secret was discovered by explorers from the Planetary League. Later, the Lucifer system was the location of an important battle in the War of Galactic Unification.
Tragic Secret
The first scout from the Planetary League reached the Lucifer System in GSC 190. The scout noticed that Lucifer 4 seemed to have the right conditions for life, and left a beacon orbiting Lucifer 8 to alert future explorers. On GSC 201.24, Captain Zoe Bonnard and the PLS Excelsior arrived in the system and made a series of discoveries.
Weak radio signals around the system belonged to a number of simple exploratory probes.
One planet had a small research outpost that still contained the remains of an exploration team.
There was a black hole about as massive as a planet that orbited in the star's habitable zone. Apparently someone on the planet had discovered how to create a black hole artificially, and the creation had swallowed the planet and all its inhabitants.
