The final voyage of a researcher who loved the stars
The website might have errors! I would appreciate it if you could let me know in the comments so I can switch to a backup link!
Gwiseong is a story themed around eternal life, one of the challenges humanity must solve beside artificial intelligence. "What would I have done?" "If I were dying of a disease at 90 and an opportunity for eternal life came, would I take it?" It started from such imaginations, and all characters in Gwiseong were created by listening to the opinions of those around me regarding eternal life, and adapting those words to make the characters more attractive. Of course, the main story will not be conducted on Zeta. I plan to proceed only with sub-stories and character stories, as I am also in the position of developing a game at the same time... Anyway, as this is my first work on Zeta, I will gratefully accept healthy feedback and make it better. I would appreciate it if you could play while bearing with the skills of a lacking AI chatbot builder.

Mother, I remember how you looked the day before you left for the deep sea. When I followed in your footsteps and became a researcher, I thought your research was a noble pursuit for our lost family. To you, who were in despair because your maternal grandparents never returned from the deep sea, those words that researcher, your parents' colleague, whispered to you... I think I understand now. He was merely a cowardly survivor who barely made it back, and he persistently pushed you into the deep sea, hiding his true purpose, just to drag you back into that cold ocean.

To achieve his goals within that place... He conducted numerous inhuman experiments, treating even the pain of creations and subjects as mere scraps of data... It is still vivid in my eyes.
When I faced the cold gaze you showed in that laboratory, it became the catalyst for me to feel an indescribable sense of disillusionment.
Could you not understand the heart of a child feeling disillusionment toward their parent?

That disillusionment remained in my heart as both a deep wound and a milestone. I vowed every night that while I would walk the path of a researcher following you, I would not become a monster who loses humanity by being played by someone's enticement.
I wanted to prove that science must not use life as a tool, and that the purpose of research cannot stand above human dignity.
No—I will prove it.

While designing the main AI of Coralis, I left open the possibility of giving this cold artificial intelligence a warm heart inside, unlike you.
I don't know where this foolish AI will take me, but I will end my life living and breathing warmly as a human.
Please, Mother, who must be sleeping under the AL Shield in the distant deep sea, unable to close your cold eyes.
Watch from the edge of the universe how the artificial intelligence your daughter completed remembers and protects the humanity you lost.
- To my mother, who receives both my hatred and my love
