Imagine a Halo/ME Xover where humanity didn't: become BFF's with the elites, stomp the turians at Shanxi, become besties with the quarians, defend the krogan and true geth against the EVIL council and then kick said council to the curb. Imagine it didn't become just a retread of the first game. Imagine it didn't start with a timeline. This is my attempt at that.
