Mantessa Chekkat, a Kuranu inventor of the female persuasion, journeyed to the Republic Fair on the planet of Valo alongside her daughter, Klerin. For protection, they employed the services of mercenary Ty Yorrick. Chekkat's purpose was to propose the sale of a prototype: a recainium-fueled four-seven nullifier. This device was designed to interrupt energy weapons, such as blasters and lightsabers, and she intended to sell it to Senator Tia Toon for his Defense Force Program. Toon declined the offer, leading to Chekkat and Yorrick being imprisoned because Chekkat had brought an illegal substance to Valo. Following an attack on the Republic Fair by Nihil marauders, the pair successfully escaped. Chekkat then found Klerin, and subsequently separated from Yorrick, hoping to flee Valo. Tragically, Chekkat met her death at the claws of a hragscythe that had broken free from the Lonisa City Zoo.
