CLASS, Read the books, it takes him about six hours to kill the Mercy and then about Five days to get off. Chief is the only survivor of the Delta Halo... Elites are kicked out, Some Grunts Join them along with The HUNTERS! now wait... something is not right here... OH WELL moving on...
Any way back at earth, TWO of the earth defence platforms are destroyed leaveing a small hole for the Cove's, who had a smaller fleet than when they attacked reach, to get through to NM the largest city on earth at the time.(but he jumps out and is looking at The North Amaircan Nations) and then plants the BOMB on a Cove' ship and then leaves soon landing on IN-AMBER-CLAD. How he gets in is a grand question to me. as well as WHO shot those ODSTs and Where they went.
Shortly after storming a brige and raiding a tunnel POMC-117 gets back in IAC and they join MERCY through to DELTA HALO. about three days into DH Elites are kicked out by the high order and then it takes a few days for them to join the humans in something i like to call, "The Union", the alliance of Elites and Humans.
Rewind to "Now" You are now an ODST and have been sleeping in your 'pod for nearly six hours. things that happend at Delta halo has not made it to earth yet(long distance calling, IT PUT A LOT OF MINUTES ON THEIR PLAN...) and because of the blast the Elites that were there, DIED and they simply sent the Brutes down to check it out.
Then alot of other stuff happens, NM goes off the maps after they start diging(Very convenint that we built the city ON the portal structere dont you think, OR mabye FORRUNNER hands at work...) and then we go through the portal and with the help of "Half-Jaw" and "Arbirter" we destroy the ARK (crap we just found it to *angry face*) and 343 goes insane killing johnson(again I thought he died in the First game...) and "Arbi" and "MC-117" make an insane jump onto INC and "Esacpe" but Master Chief goes MIA and goes into a deep sleep... I wonder how long they could last in there... And The Elites go Home stateing that now Arbirter is now their Leader and before they leave and form "The Union" Arbi sayes "IF Only It Were So Easy..." and you can see in his body language that he thinks MC is not dead... So where next...
Simple, they let you think what you want, My Ideas, Well that is how I came up with HALO KART a long time ago, and that MC is traped on a "shield world" meets his fellow spartans and they meet a Forrunner, named "The Guardian" who has with him a group of other forrunners and they look JUST like humans, There for makeing Humans the Reclaimers and all along some of the forrunners have hidden on earth and made everything happen, Leading to the SLIP-SPACE drive, Terraforming Mars, Finding HARVEST, the Meeting of the Cove's, The War, everything was by their design from year ONE B.H.L... BEFORE HALO LAUNCH... or as we call it, B.C. BEFORE the "CALLER"
