Tell us more, this is interesting.
What I can tell you is that the pagan Gods--Odin, Thor, Mars, Jupiter, etc.
All are real. They are the parents of the original Indo-European peoples that originated in Central Asia and Anatolia.
One of the earliest cities created by these people was Troy, and at that time our Gods still had regular contact with us. During the Trojan War,
the Gods decided it would be useful to create a virus that turns people in to assassins and unstoppable warriors--each created to aid rival factions in the war.
After Troy fell the people scattered themselves throughout Europe, and the Gods lost their original names.
The Great God became known as Zeus, but also as Odin and Jupiter. Some of the people that fled Troy still carried with them the viruses,
and used it as a tool to control people or seize power for themselves.
They exist in secret to this day, and work behind the scenes to gain control.
The two factions: werewolves and vampires--are bitter rivals.
