Fourth Storm

The Fourth Storm was one of the Mantis naval groups in which the Mantis Clan fleet was organized.

Creation
During the Mantis-Ivory Kingdoms War the Mantis Clan Champion Yoritomo Aramasu built several enormous ships, greater than the koutetsukan.

Discovery
The Mantis returned from the secret war and the Storm remained hidden in the place later known as the Aramasu's Vigilance. In 1172 during the Destroyer War the Mantis returned to the Kingdoms and found it.
