Hykraius is a methane gas giant that is many times larger than earth. The planet's surface is covered in a methane ocean called the Great Mother Ocean.. This ocean deadens sound and reduces vision but allows the beings of the planet to understand and speak to each other through telepathy and move their bodies by swimming and build homes with telekinesis.
The only one of their members to leave their planet was the Legionnaire known as Ganglios, on his departure they named him "Tellus" which translates to "people" in their language.
Hyrakius is a United Planets world that falls inside the territory of the Gil'Dishpan.
- Gil'Dishpan - A race of world conquering beings who have taken a portion of the planet as their own and claim it due to their intelligence, unbeknownst to them the Hykraians allow them to live on the planet as their masters due to their passive natures not weakness.
