Well, there are three common perspective for narrative. The official names are:
1st Person
3rd Person Focused
3rd Person Omniscient
1st Person is obvious. 3rd Person Focused operates like 1st person, except from a technically 3rd person perspective. It allows insight into the thoughts of one character, only, but may switch characters between sections and chapters. I assume this is how we intend to do this project. 3rd Person Omniscient allows insight into all characters at any given time. In modern literature, 3rd Person Focused is preferred, followed by 1st Person. (Aside: There's a fourth style used for scripts that doesn't allow any insight, but this is a different type of literature)
I noticed that ZeaLitY's piece was primarily 3rd-person, but had a single 1st-person pronoun slipped in--"in regions beyond our senses and wildest fathoms." Unless you plan to tell the tale from the perspective of someone in particular, I'd advise against this. I'd recommend replacing "our" with "humanity's."
