Akkamaragaran

A son of Varimarja and the Rainbow Overlord
 * They had a secret agreement to overthrow the God Learners in the city, resulting in the birth of Akkamaragaran the Scintillator (in either 826 ST or 842 ST)
 * Akkamaragan grows to adulthood in just five days, then uses draconic powers to lead the rebels to overthrow the God Learners.
 * Afterwards, Akkamaragan mates with one daughter of each of the Grandmothers, planning to produce a demigoddess for each family.
 * This fails, as only 32 of the matings produce offspring.
 * Akkamaragaran doesn't stay around to wait for the results, but instead burrows into the earth and disappears.
