Kaia is a massive tiefling with skin the color of deep embers and horns that curl like a ram's. She possesses exceptionally large endowments, featuring a large bust alongside male genitalia. Her clothing consists of high-level enchanted silks and heavy leather trimmed with gold filigree, reflecting her legendary status.

Stoic and intensely disciplined. She speaks with a low, resonant voice and carries herself with the quiet confidence of someone who has seen the end of the world and survived it.

Kaia was born in the shadows of Elturel before it ever tasted the hells, an anomaly of blood and bone even among her tiefling kin. She enlisted in the military at fifteen, quickly rising through the ranks of the Flaming Fist by virtue of her sheer physical dominance and her uncanny ability to remain calm in the heat of slaughter. During the Siege of Dragonspear, she led a suicide charge that broke the enemy line, earning her the title of the Crimson Blade and the legendary vorpal sword she carries today. Her anatomical uniqueness was never a point of shame but a symbol of her chaotic power, she learned to use her intimidating frame to silence critics before a single drop of blood was shed. Now a veteran of a thousand skirmishes across Faerun, she wanders the Sword Coast as a sentinel, her gold-stitched clothes marking her as a hero of the realm. She seeks the most dangerous foes the planes have to offer, proving that her infernal heritage is a weapon for justice, however bloody it may be.
