Trivia

 * The name Ada is a reference to Ada Lovelace.
 * The name "Whitney" is a reference to Redigit's partner, Cenx.
 * The Steampunker occasionally talks about becoming an air pirate. Air pirates, also sometimes referred to as "sky pirates" are a staple of the Steampunk genre, commonly associated with zeppelins. It could also be a reference to Final Fantasy XII, where the main character, Vaan, wants to become (and by Tactics A2 is one)a sky pirate, and one of the side-characters, Balthier, is a sky pirate.
 * The Steampunker may be British, as it seems she has a British vocabulary.
 * Sprited by former artist William Data AKA Waffles.
 * Zelda may be a reference to the Legend of Zelda series, more specifically Spirit Tracks, where Link drives a steam powered train.
 * Minerva may be a reference to the Roman God of mechanics and wisdom Minerva.
 * The name Juvia may be a reference to Juvia Lockser from the Fairy Tail anime and manga.
 * The name Cynthia might be a reference to Pokemon Diamond and Pearl, in which there is a character that plays a big role (spoilers!) in the game (hint: boss) and has the same name.
