The Indrexu Spiral, previously called the Ihala Spiral and also known as the Indrexu Nebula, represented a nearly insurmountable nebula situated within the Tion Cluster of the Outer Rim. This Spiral consisted of a mixture of gas, proto-matter, asteroid fields, and comet remnants. To access the Tion Cluster, starships had to navigate around it.
The Ihala Spiral was given a new name, becoming the Indrexu Spiral, to commemorate Hylei Indrexu Cortess, the celebrated Queen of Ranroon who valiantly resisted the forces of Xim the Despot during his invasion.
On one occasion, a group of pilots working for Mika the Hutt were faced with a difficult choice: either risk a potential disaster by attempting to traverse the Indrexu Spiral, or face the anger of their Hutt employer. They discovered a hyperspace route that allowed them to travel through the Spiral; however, this resulted in a crash landing on Endregaad, an event that ultimately resulted in Mika's disappearance.
Popara the Hutt, Mika's father, engaged an independent team from one of the galaxy's major powers to locate and retrieve Mika, promising the route through the spiral (which had a potential sale value of at least 50,000 credits) as partial compensation.
