Orion IV was settled in 2117 after negotiations with the native Delyn. A few years later, the Delyn allowed themselves to mix into the society of the colonists.
The planet is also known for having a diverse ecosystem. One creature is known as a Yogtree, a form of tree worm which the colonists and natives of the Orion system eat by frying them and seasoning them. The tree worms are often preyed upon in the wild by Orion Root Simians, which were domesticated by some natives and colonists.
