E.T.E Chronicle

In a future not so distant, corporate giants will supplant governmental authority, sparking relentless conflicts for supremacy.
The Igodra Company stumbled upon extraterrestrial remnants and artifacts in the cosmos adjacent to Earth - named [Urd], and stumbled upon an enigmatic particle previously foreign to humankind, known as the Delta particle.
The emergence of delta particles has disrupted the equilibrium of human power dynamics. Leveraging this unique delta technology, Ygodra Corporation has engineered a formidable adaptive combat exoskeleton—Aita, bolstering its military might to an unparalleled edge over the corporate titans.
To safeguard its interests, Ygodra Corporation erected a colossal orbital ring station - Gray City encircling the planet's equator, armed to the teeth with strategic armaments.
The presence of Gray City imperils the vested interests of rival corporate empires, prompting a coalition known as the "Human Alliance" to wage an assault against Ygodra Corporation. Following a grueling clash, the Human Alliance emerged victorious, crippling Gray City, yet failing to shake the unassailable supremacy of Ygodra Corporation.
Amidst the conflict, the Human Alliance seized control of the cyborg entity 01 crafted by Igodra Corporation based on Urd's technology, subsequently mastering the Delta Technology and Aita for themselves. This shattered Igodra Corporation's stranglehold on Delta Technology, sparking a prolonged standoff between the Human Alliance and Ygodra Corporation.
