EPN = E Pluribus Neo (subgroup of Zion)
CYPH = Cypherites (subgroup of the Machines)
To elaborate, EPN (E Pluribus Neo) are a group that are often considered extremists by others. If I'm not mistaken, their goal is to awaken everyone from the simulation, or at least give them all the choice to be awakened. They are sort of a religious sect based around Neo.
The Cypherites are a counter group to the EPN, they want to go back to 'sleep' in the simulation. The "ignorance is bliss" philosophy.
Plus your faction had to answer wierd Riddles in order to become a member.

hmm ok well here is my veiw of em
EPN - complete hypocritical BS, they want to honour neo's memory by destroying the truce when neo gave his own life for the truce to be formed, so they are destroying the truce by their terrorist activities.
CYPH - they want to return to their pods but they don't only wanna go they wanna bring every other redpill down with them, tryin to force their veiws upon the rest of us.
You think that there'll ever be a Merovingian splinter group?
There's been a lot of interesting talk on this, and chance's are if there was, it would either:
-A splinter Ookami group -A splinter Persohpne group The others EPN and cyph are splinter of zion and machine so it makes sense if they eventually have a merv splinter, though, at this point in the strory (with anome) i dont think there will be one, anytime soon
Hope that helps! spha x
