Thaedon

Thaedon, the Valorous, the Valiant, the Defender, was one of the Aiyu-Atma and is said to have been the strongest and noblest among them. Klython and Khyron were his brothers. At the dawn of time, when the Old Gods set to ordering creation and made war with the forces of primordial chaos, Thaedon alone stood against the onslaught of the [demons of primordial chaos] and defended the gods’ newborn [creation]. When the other gods saw his bravery, they were ashamed, and they rallied behind him and led he them in war against the [primordial demons]. Legend tells that in that time, he defeated the mightiest [demon] and torn out its blazing cyclopean eye, casting it into the firmament to roll forever in an eternal circuit around Urva and cast its light on the new-formed world. Thus was the sun set in the sky over the mortal realm. 
Thaedon also fathered the five brother gods who would later create mortal mankind, which would know and worship them as the Thaedonu-Vaati: Kothaur, Thrygon, Telaon, Gyrion, and Kaephus. It is said that these five sprang forth from his XXXXXX as he rested after the defeat of the [demons of primordial chaos]. Thaedon was in turn murdered by these five sons due to the cruel deceptions of his brother Khyron (the myths of Utara-Vaati tell that the Thaedonu-Vaati were moved to create humanity in remorse, as an act of penance and atonement for having been fooled into murdering their own father). Thus perished Thaedon, champion of the Old Gods and the defender of creation, vanquisher of [primordial chaos] who set the sun in the sky.
