Kallo Jath is the pilot of the starship Tempest, having served in that role since its early prototype days. He narrates the Andromeda Initiative's introductory briefing to the ND1 Nomad and Tempest vehicles.
Kallo Jath was born on Sur'Kesh, where he was pushed towards a lucrative but dull bureaucratic career with Parohe Aerospace. Kallo became more interested in flying the starships he was meant to be cataloguing. He eventually left Sur'Kesh for formal pilot training and joined Parohe's competitor as a test pilot. Parohe Aerospace's fervent disparagement of Kallo piqued Jien Garson's interest and in time, Kallo was recruited to join the Initiative's Tempest design team, where he test-flew early prototypes.
Having invested so much effort in designing the Tempest, Kallo was the only member of the Tempest design team to make the trip to Andromeda so he can bear witness to how the Tempest fared when in active service. He sees Andromeda as a new and exciting place, where he hopes his race can leave behind the stereotypes of the Milky Way. When speaking to Ryder, Kallo expresses loneliness at the disappearance of the salarian ark.
During the course of the game, Kallo and Gil Brodie will bicker about the modifications Gil has been making to the Tempest. Kallo believes that Gil is disrespecting the planning and effort his team made to perfect the design of the Tempest while Gil believes that his redesigns are necessary to adapt to the problems of the Pathfinder's mission. Pathfinder Ryder can side with either Kallo or Gil. Eventually, Kallo offers an olive branch to Gil by offering him the Tempest's schematics that he committed to memory. Gil and Kallo find common ground in appreciating the artistry of the Tempest's design and working together to innovate the Tempest.
