Eric Vaughan (IPA(key) /ɛr'ɪk vɔn/) is a slave owner and trader in Twokinds. He has a strong relationship with one of his slaves called Kathrin. He saved Kathrin from his Templar brother, Roderick. He views her as a sister, much to her consternation as unbeknownst to him she has a romantic attraction to her owner. Flora also thinks that Eric takes advantage of Katherin's natural naivity, but Eric revealed he never did so and is teaching her to read human languages.
Eric often depicted as being something of a pervert due to his attraction to Keidran, which is frequently alluded to extend beyond a mere professional interest- this is possibly because he grew up with Kathrin (who was bred to be sexually appealing to Humans) from the of age of 10. It is hinted he uses his female slaves to satisfy these tastes; so much so that when Mike was under the effects of an illusion and believed he had been transgendered, he feared that Eric would make him do perverted things. He is a great fan, and creator of, erotic Keidran artwork. He has recently expanded his portfolio to include Basitins. He may be a pervert, but he is a polite one.
"Eric likes Keidran. That sums it up pretty nicely."
"Eric was born into a noble family. He is extremely wealthy, but he tries to stay modest about his money. Eric has a great affinity for Keidran, and uses his vast wealth to purchase a variety of Keidran slaves in cities all over the mainland. Eric is very well-read, but he specializes in Keidran anatomy and physiology. Eric treats all his slaves very well, and most are eternally devoted to him, despite being enslaved."
- When Madelyn trashed the Kitchen, Eric, wondering what happened, comes into the room with a book that appears to be titled "How to Train Your Keidran", with the cover even resembling, slightly, a movie poster from How to Train Your Dragon.
