Although the masani is also known to some as a masan, the two are in fact different types of vampires. The masani is a vampiric spirit from India, like the masan, but that is where the similarity ends. The masani has jet-black skin and an overall monstrous appearance. It lives in burial grounds, and at night, it rises up from the ashes of a funeral pyre and attacks the first person it sees.
