The most powerful and advanced race in the Chaos universe has sent its state-of-the-art research ship into space to search for inhabited planets and, if necessary, colonize them. Years later, on their way back home, their sensors caught a strange energy fluctuation coming from the black hole they passed near.

The ship, whose all systems suddenly shut down, lost its balance and was pulled into the black hole. After a while, the ship started working again, but it was too late.

Our intrepid pilot thought they were in for a smooth cruise between star systems, but boy, were they wrong! One minute they're cruising through subspace, the next - WHAM! Their ship's split in two like a cosmic banana split.

Talk about being in two places at once! Our discombobulated pilot, now with a serious case of interdimensional jet lag, gets rescued by a group calling themselves the "Knights."
