Man, too, is a primal creature, though he binds himself with the chains named Reason and Law, locked link by link from birth. Yet, those locks can be opened, the links broken, in both the savage world of the street-slum, and in the gilded cages of nobility.
One such creature is the countess-to-be, Alia duBois, who crouches within her golden jail, a puma waiting paitently to maul her captors…
"Binding the Life Coil" is an ancient quasi-mystical technique rediscovered to prolong one's life at the expense of one reproductive ability. It is a simple magikal technique that anyone can learn (a skill or feat). The promise of near immortality or a lifespan of a thousand years or more makes everyone want to learn it.
This technique has a price though, the amount of immortality is in direct response to the strength of ones reproductive spirit. Those that have never breed will live longer than those that have. The use of the technique makes conception difficult, if not impossible. So you trade the future of your society for the chance for you to see much of that future.
