Gates the size of Mount Everest were scattered across Mercury, Earth, Mars, and a few of Jupiter's moons. These Great Gates remained closed and stood tall above the various landscapes. The life forms that lived across the solar system created settlements near and around these colossal monuments. They lived in packs and developed civilizations, some advanced, some primitive, and some in-between. This time was known as the "Pre-curser Era", and similar to the species that currently inhabit Earth today, they all sought to survive and were heavily driven by the same pursuit of expansion.
