The Astronomical Gates; a series of large, colossal engineering achievements linked together in ring-like forms, formed the barriers that separated the Akrina Galaxy into three ranks. The Outer Gate was known as the edge of the Akrina Galaxy. The area consisted of smaller stars, smaller and less inhabitable planets, and a couple of lifeforms which were mostly primitive. These planets, which were not desirable to live in, were rich in minerals such as Etil, an extremely hard and yet ridiculously lightweight metallic alloy that consisted most of the Granian ships and equipment. This alloy was so valuable that different life forms battled with each other just to control the planets rich in them.
