He wakes up without being able to see, taste or hear. Or even smell! But, after developing an eye for himself, he's able to recognize two facts: one, he is no longer human, and two, he's not on Earth anymore. He's in the middle of an asteroid field, stuck on a moderately large one with nothing around him but endless space. Heck, he's not even in the solar system! 

And now it's up to him to grow larger and stronger in order to avoid being eaten. Going by the leviathan-sized creatures swimming about the asteroid field, he has a long way to go before he can so much as try to live calmly.

Don't let the fanfiction tag scare you off. This only barely takes place in that universe since I like the basics of the lore and nothing more. It will barely feature a single prominent character, and the focus will mostly just be on the main character trying to grow himself out of danger, in the meantime denying the very idea that he could possibly be lonely. 

The first few dozen chapters will entirely focus on him growing from almost a gnat all the way to a real asteroid-eater. After that, an actual story will appear. 

Got the idea when I was reading the 2017 Darth Vader comic and my mind suddenly flashed back to that scene in the original trilogy when they're in some asteroid field and almost get eaten by a big monster. I loved that scene, and my inhibitions will no longer chain me. Enjoy, but don't take this too seriously.
