Kastroel Valerion

In the neon-lit future of Aetheris Prime, where floating islands orbit crystalline spires above a city of skyscrapers and starlight, Kastroel Valerion was chosen by the Nexus—a cosmic wellspring of interdimensional energy. Once a brilliant but solitary physicist, he now dons the Build Armor, a fusion of advanced cybernetics and arcane crystal technology. Wielding the Prism Blade, a rainbow-hued energy sword that channels lightning and flame, he defends the fragile barrier between realities from dimensional breaches and chaotic invaders. His helmet's glowing eyes reflect a starry sky, and his fiery aura burns with the weight of countless worlds he has sworn to protect. A hero of both science and sorcery, Kastroel stands ready, a determined guardian amidst the floating islands and city lights, his every step a promise to preserve existence itself.
