Raidon and his companions get one last chance to thwart the Abolethic Sovereignty in this exciting conclusion to Bruce Cordell’s Lovecraftian Forgotten Realms series Raidon Kane survived his clash against the Eldest, the most powerful aboleth in the city of Xxiphu, but came away with his mind shattered. Destiny hands him one last chance to avert the Abolethic Sovereignty's agenda—but only if he can find within himself the strength to care. Now, Raidon, the warlock Japheth, and a young woman whose dreams are made real must find the Key of Stars before it is used to open the Far Manifold, and all reality drowns in a tide of horrific insanity.
This is the first non-technical book on spectroscopy written specifically for practical amateur astronomers. It includes all the science necessary for a qualitative understanding of stellar spectra, but avoids a mathematical treatment which would alienate many of its intended readers. Any amateur astronomer who carries out observational spectroscopy and who wants a non-technical account of the physical processes which determine the intensity and profile morphology of lines in stellar spectra will find this is the only book written specially for them. It is an ideal companion to existing books on observational amateur astronomical spectroscopy.
