Description
Horn is a Grasswalker adventurer active in Zircon Tower City. Her race maintains a childlike appearance throughout life; appearing approximately 12 years old, she misrepresented her age to become an adventurer. Sociable and outgoing, she sometimes displays innocence and expresses discomfort about the mini-skirt component of her armor despite its protection. Trained in thieving skills, she prefers the title "Seeker" over "Thief."

Separated from her parents in childhood, she and her two younger sisters were raised by a Thief. After their guardian died when she was around 11, she parted from her sisters and journeyed to Zircon Tower City. She initially joined a party led by a high-level Pantherian warrior to explore a new dungeon.

She later allied with Diablo's group, guiding them through dungeons. Diablo provided her magical items: the Treasure Mini armor for enhanced speed and defense, the Ignore Mantle to improve stealth, and the Shadow Knife for increased evasion. She declined Rose's Master-Servant Contract offer due to reservations about the arrangement. She then enrolled at the Magic Academy of the Royal Mage's Association, later collaborating with Diablo to investigate student disappearances.

Her Thief upbringing granted initial abilities around level 20, including Unlock, Charm (which evolved into a potent ability designating targets as "Lust Objects"), Steal, Hiding, Hiding All, and Dictation. Eventually using the Master-Servant Contract artifact raised her level to 80, granting the Mapping skill for spatial memory and significantly enhancing her existing capabilities.

She shares deep admiration and a sibling-like bond with Diablo, viewing him as a protective older brother. This bond strengthened when she motivated him during confinement. She also possesses a unique connection to Babylon, an entity only she perceives, accidentally summoned using a sacred artifact through unconventional means. Babylon encouraged her use of the Master-Servant Contract, facilitating her growth.
