Editing Gehn

Following Keta's death during the birth of his son, he returned to D'ni, making his home on K'veer with a mute servant he called [[Rijus]]. There, he developed a rather skewed vision of D'ni culture, viewing them as gods among men, and mistaking ''regestoy'''s ability to bridge pre-existing worlds with that of true creation. Over the ensuing 14 years, he became determined to rebuild D'ni single-handedly, and tried to teach himself ''regestoy'' so that he could rebuild the catalog of Ages in the D'ni empire, adding new worlds filled with primitive natives whom he subjugated and forced to worship him as a deity. His understanding of the Art was limited, and his method of piecing together phrases from the [[Descriptive Book|Descriptive Books]] he found resulted in the instability of all his Ages.

Gehn also developed a considerable obsession with numerology, especially as it pertained to the D'ni's use of the number five. He was convinced that the number had some deeper, almost cosmic significance, and tried to force everything in D'ni culture into this view of the world. Of the six symbols the D'ni used to depict primary and secondary colors (red, orange, yellow, green, blue, and violet), he believed that only five were truly important.

Fourteen years after moving to K'veer, Gehn returned to the Cleft to retrieve his son Atrus and take him down to D'ni, where Gehn taught him ''regestoy''. However, Gehn became frustrated with Atrus's slower, more careful approach to Writing and his independent streak, which culminated in outright rebellion after Gehn's arrogance ruined [[Age 37]]. Hoping to find a more obedient helper among the inhabitants of his Ages, Gehn declared that he would marry [[Catherine]], a native of [[Riven]], his Fifth Age, whom he had been teaching the Art.  But Catherine worked together with Anna and Atrus to leave Gehn stranded on Riven.

Eventually, Gehn discovered how to manufacture new Books, and began writing a series of test Ages, finally achieving his first success with [[Age 233]]. Knowing that Riven would eventually collapse, as many of his Ages did, he began writing another Age—[[Age 234]]—where he and the Rivenese villagers would be safe, though he would never complete it. Catherine returned to Riven and helped the [[Moiety]] rebels in their struggle against Gehn's rule, though Gehn was eventually able to capture her. But he himself was trapped in a [[Prison Age]] by the [[Stranger]], who had been sent to Riven by Atrus to rescue Catherine.
