Spheretesia, a Wanderlust Fantasy

The world just started to produce mana and the magic era begins... at least that's what suppose to happen. Normally it takes time for humans to adapt and develop mana, but before they can even discover it, monsters that are already familiar with mana appear out of nowhere and start to overrun the human population. Follow our protagonist as he does his best to survive against the monsters that invade his homeworld. But is this world really where the journey begins? --------------------------- I just wanted to mention that this is the first light novel that I’ve ever worked on and I’m also just doing this for fun, so I apologize in advance if it isn’t up to par. I also drew the cover myself because I wasn’t sure which pictures were okay to use and I didn’t want to bother with it. So yea, sorry about the amateur drawing (・.・;) In any case, feel free to give feedback and thank you for reading.
