Just a side note...the closest analogue to the Typhon Pact, at least as I see it, is actually the UFP. Multi-species nation under a unified governing body with like minded ideals for the future, but with its members still retaining their distinct societies
Indeed, which is why the Typhon Pact is a true rival to the Federation. It is not simply a military opponent or an ideological opponent- in a sense the Federation is now up against...itself. This is what I find so fascinating about it. What happens next...well, everyone in-story must be quite...confused.
