Harll was a male Farghul bounty hunter (within Legends) and a member of the Crimson Nova.
Harll was a formidable combatant, more inclined to engage in battle than to strategize. Due to his combative disposition, he received a sword featuring a cortosis alloy blade as a present from a Morgukai warrior.
Later, he developed a romantic relationship with Mika, a fellow Farghul, and became a member of her chapter within the Bounty Hunters' Guild. This particular chapter distinguished itself from others through its willingness to accept contracts targeting Jedi; this ultimately drew the interest of the Jedi High Council, who dispatched four Jedi Masters to handle the Chapter. Upon the arrival of these Masters, Harll employed his cortosis sword in a duel against Mace Windu, a confrontation that ultimately resulted in Harll's death.
The Jedi swiftly overwhelmed the bounty hunter's headquarters, leading to the cancellation of the contract.
