When the Votans set out for Earth, they sought a planet they could remake into the image of their own homeworlds. Terraforming (the word borrowed from English) is the process of converting a section of a planet for Votan habitation. This includes everything from reshaping the landscape to introducing entirely new species of alien plant and animal life. However, when the Votans realized Earth was inhabited, they put their plans on hold. When the Arks mysteriously exploded, the terraforming equipment ran rampant, creating an unplanned hybrid landscape that is neither fully human nor alien.
