Roots of Corruption. Thornfall, #1

Koro T'Varan hails from the verdant moon of Lyssara, where technology and biology have long since merged. A former guardian of the Sacred Bloom a sentient forest believed to be the last relic of pre-collapse Earth Koro was chosen by the Arboreal Core, a bio-conscious entity that fused with his genetic code. The result: Thornfall, a living warrior clad in organic biomech armor grown directly from his flesh.
His exosuit can erupt into thorned tendrils, form jagged blades, or sprout protective shields in response to threat. Every movement is guided by symbiosis, his thoughts woven with the instinct of a living system. In battle, he's a walking fortress, withstanding plasma fire and pulverizing mechanical enemies with nature's wrath. But his strength is not infinite. After prolonged combat, the armor must regenerate drawing nutrients from his body and leaving him fatigued, exposed, and often in pain.
Koro accepts this price with quiet dignity. Noble and reverent, he treats life even that of enemies as sacred, and seeks balance in all things. He fights not for conquest, but to remind the galaxy of what it's forgotten: that even in an age of circuits and steel, nature still has claws and it remembers how to protect its own.
