Yggdrasil is a fourth-generation international space station, its name borrowed from the world tree of Norse mythology, which was constructed at Lagrange 1.

History

The construction of Yggdrasil began during the last years of the A.D. calendar, resumed upon the conclusion of the Reconstruction War in C.E. 9, and was completed two years later. This space station came under attack early in the current war, and was destroyed during a fierce battle between ZAFT and Earth Alliance forces on February 22, C.E. 70.
