Preenos
Preenos was an inhabited planet in the Preenos system, a star system in the Alpha Quadrant. This planet was the origin of hajjlaran, a spice.
According to space trader D'Marr, the warlords of Preenos used the spice to test their courage. (ENT: "Oasis")
This planet was only mentioned in dialogue.
This planet's quadrant of origin is inferred based on the position of its star system as seen in the star chart appearing in the Star Trek: Picard episode "Maps and Legends".
According to voiceover dialogue that was scripted for ENT: "Dear Doctor" but omitted from that episode, a very similarly named planet, Pree'nos, had a Denobulan mining facility. This planet was described as having rainforests, and inhabited by camps of Pree'. Despite this reference to "Pree'nos", the final draft script of "Oasis" spelled the planet where hajjlaran originated as "Preenos".
