From the back of the book:
A Martial Artist's power comes from life-giving Chi, which suffuses the land of the Dragon Empire. It is your duty to use your martial skills and amazing Chi powers to protect the Forbidden City from the hungry ghosts, hopping vampires and Foreign Devils who murder and steal from the innocent.
- Use an expanded Martial Arts system that is compatible with any Basic Roleplaying game. Characters may employ real-life styles, like boxing or ninjitsu; mystical styles that stem from magic; or design their own styles with the tools provided. There are dozens of styles to choose from, and over one hundred Chi Powers.
- Explore the expansive Dragon Empire, where beauty and culture are marred by corruption and decadence. Due to high concentrations of Chi, magical spirits live alongside mortals. Players can choose to be humans, spirits, or something in between.
- Reap the rewards of piety: you might become Enlightened, find a position within the Celestial Bureaucracy, or even take a sip from the Elixir of Immortality.
Dragon Lines is a game of high flying action. Characters can wade through hordes of Lesser Foes, and then duel with another Martial Arts masters. You can survive dangers which would slay ordinary mortals. Walk on water, run up walls and along rooftops, and harness the very powers of Heaven to shoot lightning from your fingertips!
