Vampire Multiverse: Zombie Wars

Welcome to a particularly dark corner of the Multiverse. In the second decade of the 21st Century, a deadly virus turned hundreds of thousands of people into Vampire-like, bloodthirsty creatures. Those creatures fed upon the Human race, driving them to near extinction. As Humanity vanished, the Vampires reigned supreme on that version of the Planet Earth. These beings, known collectively as Homini Tenebrae, became the rulers of the world. All was well, until the virus mutated, causing Humanity's numbers to dwindle. The sun began to die, and the solar system started to go with it. A brilliant Vampire scientist, Dr. Ahmed Osman, and his lover Yasmin Wachira create a Portal leading to Alternate Universes. An expedition of Vampire soldiers and Vampire scientists ventures through the Portal, in search of an Alternate Earth whose sun hasn't died, and where tasty Humans can still be found. What they find is a Zombie-infested Planet Earth where Humanity is barely hanging on. Only one kind of Undead can reign supreme in the Infinite Multiverse. The clever, ruthless and ambitious Vampires aren't about to forsake this new Earth to the Zombies, or the dull, disorganized Humans who can't seem to stop them. The reality-hopping Vampires go to war with the Zombies in order to preserve their favorite food source, the Humans. Whoever wins, the Human species ultimately loses...
