Until now, all space sims have been set in dark, tedious, empty space. Without a doubt, black holes are the most perilous of all celestial objects a warship captain is likely to encounter. Thought of by Klingon monks and other clergymen as the 'evil shades of long-dead stars', black holes are the collapsed remnants of giant stars. They have gravitational fields so intense that nothing approaching too close can escape, not even light.
Most black holes bear an accretion disk of super-heated plasma.
This accretion disk is created by the disintegrated matter being sucked into the black hole's interior. Beyond the accretion disk lies the event horizon, the point beyond which the gravitational field is so intense that not even light can escape. Just before matter gets sucked into this event horizon, this matter will often discharge high-energy radiation to the surrounding accretion disk. This proves to be an additional peril in that these released energies are enough to destroy any vessel they comes in direct contact with. Only the most seasoned warship captain should consider entering a black hole-much less battling within its interior.
