The Pale King of Hallownest, alongside the White Lady, created hundreds upon hundreds of vessels to be carelessly tossed into the abyss, where they would have to suffer an endless hell within. No mind to think, no will to break, no voice to cry suffering. Ett was one of these vessel, but he was.. unique. This vessel had a mind to think, to feel emotion, which got the attention of the Pale King and his guards. They would eradicate every and any vessel that were defects, and defect was exactly what Ett was.

Though heavily wounded and almost at the brink of collapsing, the small vessel managed to escape the King's wrath, running off to the fungal wastes where he would finally fall onto the soft, stenchy mushrooms. The Mantis Tribe, a tribe of fierce warriors, was local in the area, and by coincidence or not, the tribe's leaders - the Mantis Lords, found Ett, shivering and broken nearby.

They took him under their wing, which was unusual of the Lords to do, but they did. And soon, Ett would heal back to full health, other than the irreparable broken horn left by the King and his guards.

Instead of a fierce and brave warrior like his mothers, Ett grew a liking to the art of music, and had been given a viola to practice on. As the years pass, the small bug would soon grow up into and adult vessel, as tall the the Hollow Knight; but not as brave or experienced.

The adult vessel would now play his viola in the City of Tears, playing a simple, melancholy melody to ease the hearts of those who inhabit the city.
