Neema Farron: Neema was a character I role-played on a different site way back when, and Farron was my SWTOR legacy name.
Kohai Drenn: Kohai was the name of my Jedi Guardian in SWTOR. I based it off of the Japanese word kōhai, which is antonymous to the more commonly known senpai. Drenn was just an attempt at a believable, understated surname to avoid the all-too-common Noun-verber naming convention, such as Skywalker or Starkiller.
Korin Undoli: Korin was named after the Dragon Ball character. Undoli was a slight variation of Star Wars' very own Luminara Unduli's surname.
Abigail (Switch) Dolsa: Switch picked a new name for herself at random shortly after she was taken in by pirates, but it was meant to signify a kind of switch that was flipped off in her psyche. Her first name was taken from Infamous: Second Son's character, Fetch. Her last name is a slight variation of the Italian word dolce, meaning "sweet".
Dax Odikai: He was originally going to be Dak, but then I remembered the poor gunner on Hoth, so it became Daxis, or Dax for short. Odikai is based off of a Ugandan primary school, the name of which I just happened to randomly stumble across on the web.
Kilanaya (Keely) Jelko: Keely was the name of a female ghoul quest-NPC in Fallout: New Vegas, but I wanted it to be an in-universe nickname, so I made up Kilanaya. Jelko was a word I found on urban dictionary that apparently referred to a more intense and energetic high. I picked it because the original character concept was a recreational drug user.
Anka Revik: Anka is a Polish derivative of the name Anna, and I just made up Revik.
Jeslyn Tarquyn: Jeslyn was a combination of Jess and Lynn. Tarquyn was derived from Lucius Tarquinius Superbus, the seventh and final king of Rome.
Momoe Yuuki: Momoe was a combination the Japanese "peach tree" and "sprout", and Yuuki is a minor variation of the Persona 3 male protagonist's surname in the movie adaption.
Ana Saraya: Nothing special here. At the time, I had one classmate named Ana, and another named Saraya. The three us worked on a group project together.
Tarik Shen-Jon: I just made this one up off the top of my head, and I hyphenated the surname for zest.
