MC acknowledges odst in the pillar of Autumn. MC shoots a pure form flood and acknowledges odst. A lich transport is used and seen by the odst.Haven’t read the novelization of CE for years. Two moments in the story involve Master Chief directly, and one involved a vehicle not seen to later in Canon. Are these moments Retcons? I like all the moments, just want a clear answer. Every post has been pretty ambiguous so far about it. Everything else in the game seemed to be totally good Canon wise. I only noticed moment MC specifically did something we hadn’t seen him do. Stuff only Raven coyote have seen seems fair game for Canon continuity…
Since they bit the dust
hope that helps though.
