The Guard
Sanctuary’s builders, now it's protectors. They battle for a single purpose: to pacify the other factions and prevent further damage to the Dyson sphere. Reinforced and refitted, the Guard are a cold and calculating machine army that will save their creation by any means necessary.
Nobody knows Sanctuary like the Guard do. Their intel and reconnaissance capabilities are second to none, letting them choose exactly when and where to engage their opponents. Lacking the robust designs of EDA military hardware or the advanced shielding of the Chosen, the Guard tend to rely on overwhelming numbers of near-expendable drone vehicles, supported by a smaller complement of unconventional specialist units and powerful Experimentals. The most effective Guard Sentinels are able to keep constant pressure on their enemies, waiting patiently for them to tire before delivering the final blow.
The Chosen
A society of Post-Humans who have transferred their consciousness from flesh to machine. Believing themselves to be the next step in Human evolution, their heightened intelligence is matched only by their aesthetic sense. The Chosen wage war from their super-computer networks, leading armies of killing machines as beautiful as they are deadly.
The Chosen are the most technologically advanced of all three factions, utilizing sleek designs and personal shielding to close the distance and crush their enemies with a deadly array of exotic energy weapons. Their war machines are very specialized, but also expensive. An emphasis on quality over quantity will require managing fewer units to greater effect. Each of their Sentinels houses the consciousness of an individual Chosen, and should it be destroyed the consciousness dies with it. The Chosen are few in number, so utmost care must be taken in protecting these peerless field marshals.
Earth Defence Alliance
A human-first coalition dedicated to the rights and sovereignty of all of its citizens. Formed over a century of corruption, wealth disparity and a need for unification, the EDA rose up to become the de-facto governing body in constant opposition to the Chosen. To some, they are oppressive sectarians. To others, they are mankind’s only hope.
The EDA favors efficiency over the elaborate designs of their enemies. Commanding vast human populations and innumerable resources, their might is slow to mobilize but fearsome nonetheless. Favoring a shock and awe doctrine, expect the EDA to decimate their enemies with a plethora of destructive armaments, their brutality matched only by their reliability. Still, necessity breeds invention, and many of their best Sentinels have become masters of guerrilla warfare, using a combination of stealth technology and heavy armor to bring the pain where their opponents least expect it.
