Third Age of Obsidian — Laraine Anne Barker

"The inscription was so large that Peter was able to make it out from a fair distance. ... The words seemed to give off their own light. In a whisper, which echoed in strange sibilants around him, he read: Commanders of Light and Darkness waged war within the womb. Corruption and vicious treachery then led one on to doom. But in the Great Halls of Draining Light, in a fortifying bower, The Sleepers weave dreams while invoking the revival of their power. The friend of the One through willow shower With silver concord protects his power. But the Commander of Darkness with vicious might By false claims of kinship asserts unjust right. When the Essence of Obsidian tries to explain this prophecy to Peter by describing the word ""womb"" as a poetic euphemism for the beginning, Peter's final quest for Earthlight only becomes more difficult and confusing. And in the meantime, his and the Earthlight's enemies continue to grow in both numbers and power--until Peter discovers the dreadful truth and in his mind-numbing horror seems to be about to lose the final battle."
