Well, Nick is a given. My real name is Nicholas, after all. However, Sintari is an interesting one. I have a little story to tell with it.
So, when I was younger and I made this character here, I had heard of the star Alpha Centauri. So, lacking a surname, I decided to pronounce the name phonetically based on how I assumed it was pronounced; Sin-tar-ee; Sintari. I stuck with the name for two reasons. Nick Sintari was originally very... outlandish, much more brutish than Sytex. So the word 'sin' sounded like an amusing fit for the nature of it all. However, I changed that part of him, making him into much less of a brute and more of a social outcast going against the expectations of the society around him, so for that (with this world being a lesson to those ignorant fundamentalists), the word sin still fit, but in a different definition, since everyone thought Nick's birth was a bad omen for seemingly 'defying the natural order.' That, and his black scales only seemed to perpetuate this idea further.
So yeah, the character's name is my username, and there's the story of its creation.
