Personality

Cassion is usually pretty chill yet surrounded by a chaotic crowd/chatters, but that makes his streams really fun and unique to him, they vary so much! XD

You'll see Cassion playing a variety of different games, from solo Subnautica to playing random silly games with friends and maybe even getting crazy harizzment on Valorant. Cassion's most notable feature is the fact that his streams stay light-hearted and funny above anything. (will be finished later.)

Appearance

He has short, black and dark blue ombré hair with wolf ears to match and light blue eyes. He donns an open grey-ish, dark blue long Victorian tailcoat with a popped up collar covered in a deep blue celestial pattern on the inside which is belted loosely right below his waist.(which is really silly because right under his coat belt he has another belt for his pants.) With a similarly colored shirt underneath featuring 6 silver buttons, resembling Victorian Era gothic steampunk double breasted waistcoat. Additionally, he has a necklace with a sparkly deep blue pendent hanging from it. (will be finished later.)

Lore

Millions of years ago (possibly billions, no one knows) a star called N6946-BH1 (also known as “The Vanishing Star”) was born into a galaxy where the night sky was constantly lit up like fireworks. The vanishing star was massive, about 22x the size of Earth’s star, Sol. A couple million years after its formation, planets began to form and surround it. The planets loved their star and he loved them with all his core.

The star was vast and radiant. His light painted the dark with hues of rose and gold. Around him danced a small family of planets: Lunara, the serene moon-clad world; Verrin, the storm-hearted giant; Eila, the green world of oceans; and Korr, the loyal shard of stone that never left his side.

They weren’t just celestial bodies, they were his family. The star sang to them through solar winds, his light nurturing their skies and their seasons. Each orbit was a promise that he would keep them warm, that he would always be there. And for millions of years, he was. And they were happy.

But even stars grow old. Deep within the star’s core, something began to stir. a quiet exhaustion that he tried to hide.

He noticed it first when his flares dimmed for just a moment too long, or when his once-steady pulse flickered faintly. He told no one. Not Eila, who would sing to him with her oceans when he was sad; not Verrin, who roared with thunder in worship of his warmth.

He feared what they would see: not their eternal light, but the truth that even stars can break.

And then came the whisper.

It wasn’t sound, but gravity itself, ancient and patient. It called to him from within, a quiet pull that said: “You’ve given everything you have. There’s nothing left. It’s time to let go.”The star raged at the immortal force. It fought it every moment, unrelenting. He tried to shine harder, to burn brighter, to defy the voice. But each flare cost him more. Each heartbeat of fusion tore deeper at the fragile shell holding him together. Until one day, his light faded.

When the end came, it was not with a scream, but a sigh. One last surge of light burst from within him, flooding his beloved planets in a wave of brilliance. A farewell brighter than creation itself.

The planets felt it before they saw it. The pull. The distortion. Their gentle orbits began to twist.

As Lunara comforted her siblings with her song one last time, their star’s light turned inward.

His heart, shattered, caved upon itself. The radiance that once gave them life became a hunger that consumed.

One by one, the planets were pulled into the darkness he became. He felt each one vanish within him, their voices echoing love and comfort to the singularity until the star vanished, Lunara’s song faded, and only silence remained.

Now, Cassion drifts as a black hole, heartbroken, silent, and unseen. Carrying the memories of the worlds he loved and the guilt that will accompany him for eternity.

His gravity hums with grief, pulling not out of desire, but out of a longing to feel them again.

Sometimes, distant telescopes catch a flicker near where he vanished, a soft pulse that shouldn’t exist. Astronomers call it a coincidence. But those who listen carefully swear it sounds like a heartbeat.

A star’s apology, echoing through eternity.

Millions of years later, The Vanishing Star could not stand the loneliness any more. Fueled by shame and despair, he shed his previous identity and took on the name Cassion, a name Korr and Lunara used to tease Verrin with because he was made of gas and hollow. Cassion felt more hollow now than ever before.To put an end to his suffering, Cassion decided he could no longer reside where his family once lived. So, for millions of years, he traveled the universe until one day he stumbled upon a small system that contained a little, green and blue planet.

Cassion decided this would be where he would conclude his search and reside for as long as he could. He condensed his form and fell to the little planet he later learned was called Earth.

Upon landing, a small, lively fossa that goes by the name Aeryo and a tiny, funny sea serpent named Suijin stumbled upon him. He formed a tight bond with the pair, even altering his appearance to resemble parts of them. Finally happy, Cassion decided to explore his new world with his new family in search of others to add to it.

Miscellaneous

More Info

2025

On 25 October, he held his debut stream. (A whole 12 hours..)

On 26 October, he was betrayed over and over by Suijin </3 (and got KoScythe as a part-time mod).

On 28 October, he removed !throw after Areyohh's vicious mod abuse, making a bit requirement to throw, but this backfired terribly. (lack of tech knowledge..)
