Overall faction power Edit
tech tree completion * power of players (number of that faction players * their overall stats) * faction resources
For order, the resources flow from currently standing structures that draw power from their environment (some sort of extractors) - a direct zone control - the more coverage, the more power. Those structures need to be fed some fuel.
For chaos, overall resources depend on accumulated destruction of order and balance structures - it's a power pool that gets depleted on events like rifts and volcanic eruptions - chaos players have to budget their power expenditure.
For balance, overall resources are just the amount of RR and NRR accumulated in their main platform storages. Balance uses those resources (fuel) to power their mobility.
