Keera hails from the Jovian moon Callisto and is a crewmember working for Red Raven Towing & Salvage. He is a polyglot, able to speak most of the Sol system's languages, and his role as the Jackrabbit's communications officer is crucial to the crew's service. While translator technology exists it is often terse and mechanical in the translations it produces; linguists who understand the idioms, nuance and colloquial use of languages spoken by starfarers and planetary destinations are extremely useful members of any starship crew, and doubly so when your crew is arriving at a shipwreck and you're not certain who is on board or what language they speak.
As a Callistan, Keera is the largest member of the Red Raven crew. Callistans have long manes of sharp flexible quills and are able to extend additional quills from their back, shoulders and arms. They evolved these features because Callisto is home to many kinds of megafauna and, as they like to put it, "Callisto got some damn big predators". They have a natural resistance to the cold and don't need to bundle up quite as much as their neighbor species, which is just as well since Callistan clothing incorporates banded strip panels that allow their quills to extend without tearing their shirts apart. Their quills tend to puff out when they get mad or stressed, which given the lifeforms they share a homeworld with is entirely understandable.
Keera has a pretty relaxed personality and a somewhat grim sense of humor, and because of this he has excellent comms discipline to avoid causing trouble over a hot mic. He's not as mechanically-proficient as his captain so he tends to lend his muscle to the team in a helper capacity, but he absolutely loves to pick through salvage looking for treasures and curiosities, and has a particular interest in finding music in a salvage job. As the ship's linguist it's often his job to translate ship logs and records found on space wrecks, piecing together the story of how a ship's fate came to pass; his gallows humor helps him cope with this part of his job, as he tends to be the one to read a crewmember's last words.
Red Raven came to meet Keera on one of their earliest jobs, when the crew was just Amy and Haley. They were dispatched to tow a Callistan transport vessel with a disabled thruster back to the nearest space station. The transport ship's captain seemed very animated and upset during the service call and they didn't quite understand why until they docked the ship at their destination port, a stardock outside Saturn called Station 489B. Only then did they learn the ship was transporting giant Callistan predators whose containers were also damaged in the collision that broke their thruster, and were now loose in the cargo hold when station dockworkers opened the hatch to perform an inspection. Keera happened to be on that station looking for work and he thought the whole spectacle that unfolded was very funny, he introduced himself to Amy and Haley as a professional linguist and they hired him on immediately. To date The Station 489B Monster Incident has not been repeated.
