I chose Nymphali's name because it was the name of a Sylveon I recieved in a wonder trade. He really grew on me, and eventually he led my main party. When deciding on a form for my tulpa, I decided that my favorite pokemon would be best because I already had some sort of attachment to him, which I believed would help in the forcing process. Turns out "Nymphali" is the standard name for all French Sylveon, to my surprise! I learned that only a week ago. I still adore the name, and it just kind of stuck with me.
