Esquarium is the outermost major satellite of Aurorum, and the only astronomical object in the Universe known to harbour life. Located within the circumstellar habitable zone alongside Aurorum and its other satellites, the greenhouse effect of the atmosphere of Esquarium results in it being the only celestial body with confirmed permanent presence of liquid water in significant quantity.
Believed to have formed approximately 4.6 billion years ago, Esquarium is hypothesised to originate as a terrestrial planet orbiting the Sun directly, before being captudd by Aurorum during its inward migration as its largest satellite. This is supported by the large size of the world, as well as it being the only known spherical astronomical object in the Solar System to possess retrograde rotation, rotating counterclockwise while the Sun and all other major celestial bodies rotate clockwise. Current model in astrophysics suggest the retrograde rotation of Esquarium stabilises its axial tilt and thus climate, which might be necessary for a world to develop life.
Esquarium is the home world of humanity, the only known intelligent life in the Universe. Archaeological evidences suggest that anatomically modern humans first appeared about 200,000 years ago, the outward migration of which gradually supplementing other archaic humans as the dominant species of the world. Since the beginning of the Holocene epoch 12,000 years ago which marked the beginning of the Neolithic Revolution and agriculture, human activity has drastically changed the geography and biosphere of Esquarium through urbanisation and deforestation.
The contemporary Esquarium is divided in geopolitical entities, nation-states, administering territories. The world today is linked together through trade and globalised culture, and by international bodies working towards peace, such as the OEN and EC. However, it still remains a very volatile place but since the mid-20th century has seen an unprecedented period of relative peace brought by the advent of globalisation and nuclear deterrance. Significant tensions still remain between groups and ideologies competing for hegemony after a Volatile Century.
