Invasion Earth - Forward Base of Operations

This mother ship is the Forward Operation Base for the invasion of Earth. These being are not interested in materials for personal gain, but want to control all intelligent living being in order to make the universe an orderly function instead of being chaotic and random. In this way the all material wealth can be used for the purpose of extending the control through out the universe.
The invading troops and other equipment are independently AI control machine and robots, only a small number of organic life forms are needed to command the operations for invasion.
This Mothership is so advanced that while landing it can dig out the shape of the craft and pulverize the soil so that it weight is cushioned. So precise in it's operation one cannot see the difference between the soil and the hull.
A living membrane covers the ship which makes it stronger than titanium. This membrane is self healing and can hold up to many hits that other ships cannot survive. Surrounding the hull is a electro static force field that help in reducing the number of times the membrane need to heal. The membrane feed on light just like plants it uses photosynthesis.
