The archive has two files. They share the name, so only one can exist at the \mods directory. It should probably be the newer one.
EDIT:
I looked through the .dm file. I'd tone down some of the abilities, like Wind Dancers defence. 19 is awesome base stat; 15 should do. Remember how the Vampire Queen was supposed to be just another chassis for cheap magic paths?
Not a bad mod. I didn't like the Bloodhound's description, though; a rapid dog is not that good a gift. The rapid beast should be what has become of his familiar after he received his infernal powers.
