Important information
Just so you know the Spartan names correspond to their powers but it's not entirely all there powers an example would be Phillip he is referred to as earth but his powers are actually allows hims to control any element that is found in the earth such as dirt,rock and iron this applies to all the Spartan in oblivion team even main character even though he controls Dark matter and the system allows him to gain new powers each power can grow to more than the name suggests.
After being transported main character will go by his Spartan name and not his original name or the original name of the body he inhabits.
The System appears during the first chapter but will not be seen again till after the covenant leaves earth since this is the only time main character will not be busy on a mission its also why Destiny has not mentioned it to him since hee original peepose was to moniter Dark to keep the UNSC informed if Dark goes against orders untill the system intervened and change her this still means she has to report his actions and orders to them whioe he is on missions.
I forgot to say where the items come from now as the system is designed to make the user stronger and to accommodate this it creates items using the Divine Points that the MC has now these items are not all from the Halo universe they can come from any universe ever imagined or created however any defective things such as the viruses from resident evil that turn people to monsters will be fixed using the system but they will cost more Points than getting one that is identical to the ones in that universe do not the MC will never buy the Defective versions only the systems perfected ones will be purchased by protagonist however the defective one will still be in the system store I will not say the reasons for that you will know when the time is right.
There are also items that are created by the system as well such as the ship the MC gets From his mission but they will cost more than items that are from other universes.
Main characters
John Aka Spartan Dark(John is his name before being transported into the halo universe the name of the body he inhabits will not be revealed yet)
Philip Aka Spartan Earth( member of oblivion team)
Victor Aka Spartan Fire( member of oblivion team)
Jess Aka Spartan Water( member of oblivion team)
Alice Aka Spartan Wind( member of oblivion team)
Lieutenant Lucy Keys( note this character does not exist in the original game she is the second daughter of captain keys and is Oblivion Teams handler)
Side Characters
Master Chief ( I know he will appear alot during the halo 2 segment of this since during this segment both the main characters and Master Chief will be going through the same events but after that he will not appear as much)
Sergeant Johnson (will be seen during the events that happen in halo 2 but will later be seen rarely)
A/N I will edit this as more character and information I deem important appears and for those wondering as off December 15th there is 16 Chapters on patreon I will point out that it's not mandatory I will post the chapters here once I can guarantee patreon is a segment ahead which should be by Tuesday the 19th for those who are can wait I have yet to decide weather to have special chapters for patreon only but if I do it will be nothing that will change the plot just extra that will ether show events from another prospective that's not apart of oblivion team or those they interact with an example would be a chapter on the meeting of UNSC Command that decided Darks fate but as I said I am undecided as it means I will have to write them in away that they will be considered extra and not important to the plot with that i thank you for reading and hope you enjoy.
