If anyone remembers the last cut scene of Reach,
(SPOILERS)
Noble 6 dies and his helmet lies on a field of rich plant life and beautiful scenery. The year on the bottom right corner is 2589 which surpasses the timeline of Halo 5 Guardians so could this mean the ending of Reach has ties towards future halo games? The ship or structure in the background looks more human than alien so could this mean humanity defeats Cortana and her Guardians? Or did Bungie simply just choose a random year?
Let me know your thoughts.
