Necromancy: By some it is considered as nefarious black arts and by others a vault of opportunities, the very key to the secrets of life. A substantial part of the necromancer’s practice is devoted to undeath; a state in which one is neither alive nor dead. Unbeknownst to the general populace there are three ways in which undeath can provoked, and the curse of unlife bestowed upon the recipient.
This is a system for balancing magic based on two negative aspects: A) Magic creates “noise” that those sensitive to power will notice and B)Magic is channeled through rifts to other parts of reality OR other dimensions/planes/what have you and those rifts can get out of control…
"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.
