Answer:
narrator
Explanation:
the person telling and describing the story is known as the narrator/author.
I believe what this passage foreshadows is that C. Rome will suffer danger and destruction.
You can see in the excerpt that no good things are happening - there is a fire, and something is burning, and people are afraid - so obviously, it doesn't mean that it is going to prosper or be renewed, when something so terrible is happening. One slave cannot destroy an empire, which is why that is incorrect too.
I think you meant external conflict?
It would be person V.S. person or Person V.S environment
Generally, epics are very long(like book length).
