Alphosa

Alphosa was a planet located in Federation space in the Alpha or the Beta Quadrant.

The planet was home to a large Orion Colony during the height of Orion civilization in the New Days. Cities survived into modern times, and showed the beautiful classical styles of Orion architecture. 

The planet became a Federation world by the mid-23rd century. During the Four Years War between the Federation and the Klingon Empire, in reference stardate 1/9504 (circa 2253), an Orion merchant vessel was transporting dilithium to Alphosa when it was intercepted by a Klingon task force and was destroyed, triggering the Laxala Incident.
