Arus is the home of the Arusian race and the first planet under Voltron's protection from the Galra Empire.[1] It served as the resting place for the Castle of Lions for at most 10,000 years.


Little is known of Arus' history. At some point, the Castle of Lions came to rest upon planet Arus with Allura and Coran in a deep sleep inside its cryo-pods, and the Black Lion locked inside its hangar. At some point, the Arusians came to worship and believe in the existence of the "Lion Goddess" as told by "the ancients", and carved symbols of the goddess around the Castle. The Castle became embedded in the ground of the planet and structures were built around it.[2] The Castleship and its occupants are awakened once Lance, Shiro, Keith, Hunk, and Pidge arrive in the Blue Lion. The local Arusians soon send Klaizap to investigate the Castle after witnessing Voltron battle Sendak's warship.


Arus is a hospitable planet full of water, green plant life, and a safely breathable atmosphere. The Castle of Lions is located in an area of rocky cliffs near a body of water, surrounded by forest and grassy, mountainous lands. The planet seems to have a moon larger in size compared to Earth's moon, noted that it could be closer in distance to its moon as well.[3]

Though Earth and Arus share a lot in common, both are tremendously far away from each other;[3] Arus is located in sector of the universe called the Javeeno Star System which is full of constellations unfamiliar to humans, and sits way on the fringes of the Galra Empire.[2][4][5] It has a nearby asteroid belt called the Zolar asteroid belt.[5]


Arusians are small bipedal aliens with two or more curved brown horns who live in a village by "Gazrel Hill". They appear furless, tend to be pale in color, and have thick tails. Their toes are dexterous enough that they can move across the ground just by moving their toes alone.[1]

The Arusian culture appears to be a primitive one with little advanced technology. They believe in the "Lion Goddess" that "the ancients" spoke of.[1] The Arusians are so fearful of the Goddess that if they believe she is angered, they decide they must willingly burn themselves alive in sacrificial fires to appease her.[1] They believe Voltron is a "mighty robotic angel" sent to destroy them. The Arusians have a basic political structure and small organized military, in that they have a king and his subjects, as well as a class of warriors.
