I try not to be negative towards others opinions or theories, particularly when it’s obvious a lot of work went into it. Firstly thank you for the read. Secondly, it makes very little sense. One cannot kill entropy. The darkness in destiny is meant to represent entropy. It is one of the foundational cornerstones of the game. The “light” is diametrically opposed to entropy. Resurrection vs death. Disregard whatever grimoire card you are reading and try to understand the base concept of the game. I firmly believe guardians are meant to have been the antagonist in the original story, working against the natural order of the universe, using the power of a corrupt alien intelligence. After the rewrite, there was no dramatic reveal. Bungie has been trying to rectify this concept since that time and that is why you have the convoluted story. This is not meant to be a negative commentary about you or what you present here so I hope you don’t take it that way. Until the developer can rectify the inherent problem of having a race of immortal warriors who serve an alien intelligence that they don’t actually understand or communicate with, well you wind up with convoluted story plots that ultimately lead no where. That’s why you have stagnation in terms of actually moving the story forward.
