Akalo

Akalo is an alternative name for Archa Nine, the ninth planet in the Archa system. An organic, forested planet, it is populated by the Akalouthans, a technologically primitive people. Their society revolves around the Divine Light, a powerful object that fell from the sky several hundred generations ago.

Animated continuity
An "epic battle" was fought over a "potent energy source" on Archa Nine, forcing a Decepticon ship involved in the battle, the Twilight, to crashland on the spider-infested seventh planet, Archa Seven.
