Casting out of House Hyruko

Disbandment

A traitor house is discovered.

In the year 179, it was revealed that House Hyruko had been corrupted by the forces of Seras and formed a secret pain cult in their family lands.
  Upon their arrest, Lord Hashimoto, proclaimed that the house would be placed within the largest ship in their family fleet, the Kaiten, and set adrift in the Sea of Shards. Not surprisingly, the ship was claimed by the sea. In the years since, rumors of sightings of the Kaiten have spread through the Sea of Shards.
