I am a special zombie. - A fantasy apocalypse!

My name is Zei, and I am a zombie. Unlike other zombies, I maintain control over my body... or at least I try to. I thought a zombie apocalypse was the strangest thing I had ever seen, until one day, an Orc appeared in front of me, and I was saved by an Elf. What are fantasy creatures doing in my world?! Are they related to the zombies?! Seeking answers to my questions, I decided to investigate on my own. Elves, Dragons, Orcs, Goblins. All kinds of fantasy creatures are invading my world. Zombies are no longer the only threat in my world.
