After reading this
, I realized that Keila, the ONLY OTHER vampire introduced in Adventure Time, has about zero development in the miniseries. So I decided to create a headcanon that links the two vampires together and implies what kind of history they may have. Fitting it all in one page was a pain.
I doubt they'll ever appear in the main series, so I did my best to give the best gift any creator can bestow upon characters: Story and Personality.
