YGDR S/L

The Yamato-Goddard Dynamic Reactor (State/Location) power system is a Quark inversion power plant that powers Valhalla. It's very heavy and had to be 'grown' rather than constructed.
== Behind the Scenes ==
The YGDR S/L system's name is also a reference to Yggdrasil from Norse mythology, a great tree that stood at the center of the world.
