Quest to Oblivion

A twenty-five years old man saught for the demon that caused him to be transported in a different world. After knowing that the demon died hundreds of years before his wake and that the people he once was associated with were still alive, they decided to meet one another and to reunite. But upon percieving that the demon's death and the transportation of people from different world like him and his friends matches the lore written in the codex of a fallen church, they went off their ways and pursued for the real meaning behind the book only to realise that there was a deeper story behind the lore that involves even the smallest life form in the world they're living in. Join their perilous voyage as they complete the Quest to Oblivion. ps. this is the first time I'm writing a novel. I'll apologise in advance to my future grammatical errors and typos :'>
