[url=http://typemoon.wikia.com/wiki/Arcueid_Brunestud#Other_Appearances]Archetype Earth[/url]: If Gaia is the planet's subconsciousness then it could be said that Archetype Earth is it's consciousness. However, during the conflict unless she is required Archetype Earth will be sleeping inside Aruceid [s] who will probably just be spending her days showing up at Shiki's school and going on dates with him.

Primate Murder: Also known as the Beast of Gaia, Primate Murder is a white dog classified as a Magical Beast born as a Counter Force from Gaia with the sole purpose of killing humans. It has absolute authority over whether to kill a human or let them live. Gaia will only unleash Primate Murder as an absolute last resort 

Notable Weapons/Strengths: 

Counter Guardians: Humans who have made a deal with Alaya, the will for the survival of humanity, to serve it as a counter guardian in return for being granted one miracle. 

Heroic spirits: Spirits of humans who have reached the status of heroes; they are placed outside the cycle of transmigration of the soul and ascend to an existence closer to a Divine Spirit in order to become a power that protects humanity. 

Staging Ground Bonuses: Heroic Spirits will gain a considerable boost to their power if they are battling in a land or against forces originating from a land where their legend is well known. For example, Heroic Spirit Arturia, being the embodiment of King Arthur, would receive a boost against Britannia. 

Important: This faction does not claim any land (The counter guardians only really resides on Semiramis' Noble Phantasm, The Hanging Gardens of Babylon (a floating fortress in the sky). They only move into action on the impulses of Gaia and Alaya, which in turn will only order the forces to move if the conflict threatens to become apocalyptic (Or in Alaya's case, if a non human race is about to win). Other than that, the Counter Guardians may participate in battles if they wish, but the Heroic Spirits are absolutely forbidden from taking any sides.

Of course, the factions are free to try and attack the hanging gardens of babylon, but woe betide those who dare attack those who serve the will of humanity and the planet...
