A man was killed somehow and brought back to life. He, uniquely, remembers everything about Death, from the skeleton on the horse that guided him, to the afterlife itself. And the annoying bit where he was wrenched from his jacuzzi. He now has penned the instant best seller, entitled 'To Death and Back: My adventurers beyond the grave.' OR IS IT? Is this man telling the truth, or simply a very good liar? Is it all a fraud?
What if a mage passes his powers on to his firstborn son, and a female mage to her first daughter, leaving the parent POWERLESS? A plain mortal, a sorcerer no longer, all wizardly might gone?
Or: what if a female wizard recieves the power of a mage who sires a child with her? Could lead to promiscuous witches and overly careful mages.
