The Key to Creation

The Key to Creation brings the Terra Incognita series to a satisfying conclusion. The two warring groups have an experience that is closely modeled after the Arab/Israeli conflict. Or perhaps even the Suni/Shiite division. Each group is descended from a brother. Their relgious histories are similar, however, they bicker over the minor differences. Each side sees the other as heretics. They see similar areas as holy, yet they constantly fight against each other. The devout religious leaders are more concerned with their dogma than the truth. When a religious leader sees evidence that contradicts his religious understanding, he destroys it.
The main threads of the story finally connect and wind down in this final novel. The two warring factions have a huge battle with great destruction. Two expeditions both succeed in finding the source of their society. They awake the "father" of the founders of all their religions. He and his fellow beings are worshiped as gods. However, he admits that there are others with more power than him. He uses some of his technology to quickly return to the site of the great battle and help order peace. Both sides reverence him and finally put aside their differences. It is with great difficulty that they do this. They also maintain some of the keys to their respective religious, merging their established iconography, rather than than destroying it. Could this be a possible template for middle eastern peace? (Though it may be difficult to get Abraham to come back to order it.) Endless tit-for-tat revenge seeking will never be appeased.
