" The Necrotelicomnicon was written by a Klatchian necromancer known to the world as Achmed the Mad, although he preferred to be called Achmed the I Just Get These Headaches. It is said that the book was written in one day after Achmed drank too much of the strange thick Klatchian coffee which doesn't just sober you up, but takes you through sobriety and out the other side, so that you glimpse the real universe beyond the clouds of warm self-delusion that sapient life usually generates around itself to stop it turning into a nutcake. Little is known about his life prior to this event, because the page headed 'About The Author' spontaneously combusted shortly after his death. However, a section headed 'Other Books By the Same Author' indicates that his previous published work was Achmed the I Just Get These Headaches's Book of Humorous Cat Stories, which might explain a lot.
