In late 2373, Latralis was part of the Kartaali contingent the USS Cantabrian picked up to ferry to Earth for the Federation-Kartaali officer exchange program. (Star Trek: The Cantabrian Expeditions: "The Fire in Which We Burn")
Latralis and his commander Vehayz Ca'l beamed aboard the Dark Starship with Cantabrian commanding officer Noah Wrightson and others to capture Samantha Delaney after the Cantabrian's destruction. Both assisted in apprehending Delaney and her cohorts. (Star Trek: The Cantabrian Expeditions: "By All Means Necessary")
In 2376, Latralis accompanied Ghikadi Thall and their away team to the supply depot in a cave on New Bolarus after the USS Determination was damaged and forced to land on the surface by a Vendoth scout ship. He demanded less talking and more action during the mission. Ghikadi felt Latralis believed he was solely in command and the Kartaali was taking command a bit too seriously.
He was one of only three survivors from that away team to get back to the Determination. (Ghikadi Thall was attempting to rescue the Bolian colonists.) He was uninjured but quite upset about the experience. (Star Trek: The Cantabrian Expeditions: "Howl")
