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?
The extra-planar citadel of Ansern is named after its mage-founder. Ansern discovered the means to traverse the planar gulfs and created the citadel as a haven for his disciples in the art of planar-exploration. The disciples of Ansern continue his work and explore the countless worlds opened up to them by the work of the mage. They are cataloguing everything they discover in preparation for the greatest volume ever written: the Mondopedia, a book detailing many of the worlds. But the countlessness of the planes means that their book will never be finished.
