Tython
The location of the Jedi faction's first temple (or so some claim) this Deep core world planet is so steeped in the Force, that is is lush with greenery. Mountains, grasslands, the only thing it's missing is - people.
Unless it is Jedi come to study at the temple or hold secret meetings.
The Martyrium of Frozen Tears is located here and it is known for having at least 2 moons.
