Trillillial, of the Skies, was one of the Elder Gods and was very close to Her sister, Isune. She and Xyl were lovers and Trillillial admired Him for His passion for harmonic beauty and aesthetics.
Trillillial belonged to the Fourth Circle of the Divine, also known as the Artists. When the Book of Trillillial was discovered, it taught mortals about the Circles of the Divine and helped enlighten historians as to the roles of many of the Gods in the time before the Elder Wars.
