Kally is a 17-year-old scout in Neeba's adventuring party, hailing from an impoverished hometown. He joined the climbers primarily to secure resources and aid for his struggling community. His combat style employs street-smart tactics and ninja-like agility, specializing in thrown weapons with throwing knives as his preferred armament.

During the group's ascent, Kally uncovers critical information about the true nature of Pazuzu's caskets, a discovery that directly leads to his death at Pazuzu's hands in the ninth episode. Earlier, a doppelgänger impersonating Kally attacks Neeba, but Neeba identifies the impostor because it used its right hand; Kally is left-handed.

Following his death, Kally appears as an illusion. In the seventh episode of *The Sword of Uruk*, an illusion of him manifests alongside Ahmey. Another illusion appears before Might the Fool, who perceives Kally as her mother figure. This connection stems from Kally being the first person Might saw after he inadvertently opened her coffin and woke her prematurely, causing Might to adopt a protective stance towards others. Kally's ultimate aspiration of improving his hometown's conditions is fulfilled posthumously by Fatina and Utu during the epilogue.
