This is the final scene for which I created the Trigono plane. Similar to my Misty Valley Observatory, the base is hidden in a valley somewhere in the mountains. While it's not a secret place, it's still a restricted area due to the scientific character of the facility. Surveillance drones patrol the sky above from small drones bases hidden in the surrounding mountains. It's a peaceful valley with a secret beneath, where nature's beauty and modern technology unite to guard a vital secret, hidden away from prying eyes.
