The trial of Existence was the first trial, and it was issued by no other then your soul. It was through this trial your soul translate the information gained on the said trial and then awaken the power of higher consciousness. The soul grew in power the more you age or to be exact the more experience you gain the more mature you soul becomes.
Information could range from experience to emotion, for example. The Aether from an Aurora ranked individual usually come in an ethereal milky white colour, then when they advance to the rank of an awaken they gain an additional colour, but the color depends of the emotion driving their exousia at the moment. For example he felt rage, his milky white Aether will be laced with red, or fear: yellow. But if he advanced to a higher realm the colour that first appeared when he manifested his exousia becomes permanent, the emotion becomes permanent.
Back to the trial, your soul only requires a specific information before it could manifest your exousia.
So in the case of Eclipse it was death.
In the cold expense filled with nothing but flowing darkness and a cold corpse which was slowly but surely decaying, with pieces of decayed flesh drifting off, until something. It seems as if something heavy descended on the body of the corpse as the body got dragged down a little. The something supernatural happened, or maybe not the world in itself was supernatural. The body of the boy started stitching itself right, it was if time was reversed, skin began to grow like moss on the now skinless corpse, as the skin fully regenerated the body temperature began to increase, the skin gradually regained it's colour as breath returned.
With a gasp Eclipse woke up, coughed for some time then blanking stared ahead.
"Aren't I supposed to be dead" he wondered aloud but nothing answered him except for a sudden longing feeling in his heart.
A vague feeling of longing called from the darkness in front of him telling him to move forward but he hesitated, but the feeling became stronger.
"It's not like something even going to happen, I have already tried moving forward before". He spoke slightly annoyed as he stretched his hand forward ready to prove his feelings wrong, he struck his hand out with force of his entire body, as his head touched the darkness it parted allowing him to fall right through onto the other side, the darkness closed behind him without a sound remaining in it's pristine silence.
Eclipse fell through with a yelp as he appeared in a open expense with darkness and light, the only source of light being the gray paper coloured box with many rotating markings, the box itself was also rotating slowly. The feeling of longing became increasingly stronger, he felt as if he was looking at a long lost part of him, his body began to gravate towards the box.
"This should be my soul plane". Although he was ignorant at a lot of things, he still knew some things, like for example the soul plane where his soul and Aether was located.
Outstretching his hand his fingertips touched the box.
"Just like paper". That was his thought before he lost consciousness again.
...............
The room was small, with tatami mats covering the floor. The walls were made of thin, worn plaster, and the windows were covered in old, worn shoji screens.
The air was thick with dust, and cobwebs clung to the corners of the room. A single, flickering candle cast a dim, warm glow over the space.
In the center of the room, a low, worn wooden table stood, covered in scratches and scuffs. A single, battered stool sat beside it.
Against one wall, a futon lay unmade, its thin blankets rumpled and stained. A small, rusty kettle sat on a small, earthenware stove, its metal surface corroded and flaking.
On the opposite wall, a small, cluttered shelf held a few worn books, a broken clock, and a faded photograph. The shelf was covered in dust and cobwebs.
In the corner, a small, rickety desk sat, covered in scratched and worn papers, and a few broken pens.
The room was dimly lit because of the existence of a single small window, and the only sound was the faint breathing of a young boy with black hair. The air was stale and musty, filled with the scent of old dust and decay.
The family's belongings were sparse, reflecting their poverty. A few worn kimonos hung from a wooden beam, and a small, woven basket sat in the corner, filled with a few scraps of cloth.
The room was a testament to the family's struggles, who had made do with what little they had, and had managed to create a small, cramped space that was, somehow, home.
On the futon the boy stirred awake revealing his brown eyes— or eye, one of his eyes was covered with an eye patch, the remaining eye was filled with confusion then realization. Looking around he muttered.
"It seems I passed the first part of the trial". The trial was divided into two parts, one was issued by the SOUL called the trial of existence, the other by the dairy called, called rite of passage.
