In the eternal, formless depths of the Ethereal Plane exists beings of Thought and Will, their constant task infused to the core of their being to observe and protect the great Boundless Threads; the platinum tethers of Fate and Time inextricably bound from each life in every corner of Anaias to an unknown corner of the Ethereal Plane. The length of the tethers bound to the life essences on Anaias were known as the Unknown Below, while the opposing anchors bound to the far reaches of the Ethereal were known as the Unknown Above.

Such a Thought had been observing the ancient tethers when a shocking crisis occurred: the tethers began to unravel and snap from their anchors in the Unknown Above, falling to ruin in the Unknown Below. The world of Anaias from which the tethers originated had been fractured by a devastating eruption of Mana, releasing forms from their tethers before their due time. Distraught by the reckless chaos, it moved its existence nearer the falling tethers to investigate, finding their formation to contain hundreds of millions of individual Threads, all cut down to wilt in oblivion. To the horror of the Thought, other nearby tethers were taking on a sickly green color, rotting quickly, disintegrating from the center toward the ends. Others still were freezing in place only to shatter violently at the motion of their massive size.

The Thought witnessed this destruction with a mixture of horror and curiosity, its instinctive need to understand what threatened the tethers and the countless Threads within. As it neared a falling tether, choosing to suddenly exist near the periphery of the falling terror, a tiny corner of the miles-wide jagged gash atop the severed tether passed through its empyreal form. This touch brought about a wealth of sensations new to the Thought: falling, screaming, fear. The Thought then opened its newfound eyes, finding its body enclosed in a finite space, pushing outward as an instinctive reaction. In the light that shone through the opening of the space, later known to be a sarcophagus, it saw others like itself; Thoughts given Form. As it emerged from the sarcophagus, one large form moved through the others from behind, parting them as it passed. Its massive form is covered in jet-black armor covering most of its features except for its mouth and slightly bearded chin. Adorning the right breastplate was the demonic symbol of Sar, calling itself the Obsian Iter.

The Obsian Iter reached out his gauntleted hand to touch the shoulder of the Thought, its dark energy pulsing through the contact bringing searing pain and endless memory. This was the shared memory given at the moment of dark birth of the peoples of the Rictus. The Thought, now called by the name Navaetí, would know its responsibility to the world of Anaias to correct where Fate and Time had been misaligned by corruption of the Shattering. Navaetí rose up from his shadowy entry to the world, adorning his lean, pale form with shadowy robes, hooding his eyes glowing faintly with red.
