The Hy'thor pirate group was a pirate organization operating in Mieru'kar sector during the Rebellion era, led by the criminal Ompiach. Under Ompiach's command, a leadership council managed the group's affairs.
For a time, the Venithon Twins worked for this organization. Although they were officially under the council's orders, they held a great amount of power on some of the council members.
Ompiach sent the Venithon Twins to create a treaty between the Hy'thor pirate group and pirate Safonne Pendonn. The meeting ended in a naval battle between both of them.
