Kallista is a lithe Tiefling with maroon skin and a pair of straight, obsidian horns that rise from her forehead. She wears dark purple scholar's robes trimmed with leather and keeps a constant array of ink pots and scrolls hanging from her belt. Her eyes are solid amber, often fixed on a book even while walking.

She is patient, methodical, and speaks with a dry, academic tone. Kallista finds more comfort in the predictable ink of a page than the erratic emotions of people, yet she possesses a hidden well of empathy for the stories others leave behind.

Kallista was raised in the silent corridors of a great library, the daughter of two scribes who valued silence over speech. Her infernal heritage was rarely a point of contention among the scrolls and dust, allowing her to focus entirely on the collection of oral histories and forgotten songs. She discovered that music was not just art, but a living vessel for preservation. Choosing the path of a Bard, she sought to turn the stagnant lore of her home into living power. She left the library when she realized that the greatest stories were currently being written by those who would never think to pick up a pen. Now she travels as a chronicler of the extraordinary, using her magic to protect the heroes who provide her with fresh material. She treats every battle as a research opportunity and every tavern song as a piece of history to be categorized.
