Type VII Invader Mothership

A Type VII Invader Mothership is a form of spacecraft developed by the Xantirians, the formerly dominant civilization inhabiting the planet Kepler-186f.

Connection to Emanuel Fialik
Sometime before the first complex lifeforms came in to existence on Earth, Emanuel Fialik visited Kepler-186f in order to consume the planet's souls and resources. Kepler-186f's inhabitants were, at the time, the Xantirians; a species native to the planet. This mothership was designed and developed solely by the Xantirians in order to colonize other worlds.

Emanuel Fialik, after successfully overthrowing the entire Xantirian species, went in to hibernation in Kepler-186f's core. After 70 years had elapsed, he returned to the surface and hijacked a Type VII Invader Mothership which he used to travel the stars for millions of years. In 1804, Fialik used the vessel to travel to Earth; he landed in Greifswalderstraße, Berlin and hid the spaceship via unknown means, after which point, he began a bloody killing spree.
