The first Age encompasses the time from Creation until the rise of the Great Kingdoms of mortals. From which point on one should start speaking of the second Age is debated, some say the first age concludes with the creation of humanity, some argue that humans still lived in simple conditions for centuries before the first of the Great Kingdoms rose.

It is agreed that before everything the Astral Sea already existed. Then came the Thought, the thing that willed the Universe into existence. Some see it is an otherworldly force, beyond even the gods, some understand it as a great Circle, others yet deny the existence of the Thought altogether and said the Universe came into being by a spontaneous Ordering of Essence. Initially the Thought conceived of the gods and of matter, coalescing it into a great swirling sphere of chaos named Pangaea, it is said that afterwards the Thought unmade itself.

Realizing how fickle the mind is, how easily what was made could be unmade, how easily a stray thought my crush through the universe like a great arrow, how easily a distraction could change what was seen as perfect, it unthought itself. Wanting to protect immaculate creation over its own existence, it scattered its Essence over all that was, its mind undone, its child forevermore extant. _{Commentaries on Creation by Sidhael Alrantora}

Over time Pangaea was separated into an upper and a lower layer. Those former being those of pure energy, where the gods reside, the latter being those of material. In the beginning those were the four planes of earth, fire, water, and air.

Collectively the gods took some of each of the four elemental planes and, making a pocket of space between them, created the world of Initium. There they created the elves, the first mortals.
