There are a lot of grammar mistakes in the first chapter.
For example, "An atrocity and abomination occurred in the city of Loz, more precisely the tavern Moondust."
The line
"An atrocity and abomination occurred in the city of Loz, more precisely the tavern Moondust."
should be changed to
"An atrocity has been committed in the city of Loz. Or more precisely, a tavern named Moondust."
You get rid of the word "abomination" because the word abomination means a thing that causes disgust or hatred. This means you create an abomination because it is a thing. You change the sentence to "An atrocity has been committed" because an atrocity is an extremely wicked or cruel act, typically one involving physical violence or injury. This means you commit an atrocity because it is an act.
I can also see that you used the word "occurred" to turn it into present tense. However, since you started the story after the main character has already arrived at the scene and the deed has already been done, it cannot be present tense.
The line "Or more precisely," is a dependent clause. This means that it enhances and depends on the independent clause "a tavern named Moondust." Finally, you add the word "named" between tavern and Moondust so that you know the subject, tavern, is called Moondust.
This is just one line, and there are many more grammar mistakes.
