But a short introduction could be: It's an Elfquest fan comic, a "dôjinshi", introducing vampirism via a so-called "puddle of Magic Gone Bad" into an Elfquest environment. Black Moon is the son of Rayek and Winnowill, a concept amply tried, as I later found out :o)
Also, I use the term "Gna?" off-line instead of "WTF?", because it is that much easier to pronounce. Gna is sometimes the only fitting response, and when it doesn't suffice, gnaah! can be used :o).
TL;DR:
It's me Elfquest fan comic. "Gna" is just sth. I say.
