Mentor (Rhetor IV)

Mentor is the fourth planet from the sun of the [Rhetor system](https://robertsspaceindustries.com/galactapedia/article/0ODlqMJXmP-rhetor-system), [United Empire of Earth (UEE)](https://robertsspaceindustries.com/galactapedia/article/VyvyKxy4v6-united-empire-of-earth). Located on the far outer edge of Rhetor's green band, Mentor has a harsh, cold year-round climate that keeps its inhabitants mostly indoors. Its academically challenging universities suffer from a higher dropout rate than those on [Reisse (Rhetor III)](https://robertsspaceindustries.com/galactapedia/article/0QljXw43Ev-reisse-rhetor-iii) and [Persei (Rhetor II)](https://robertsspaceindustries.com/galactapedia/article/0ODlqM6zKO-persei-rhetor-ii). Mentor is also the site of the UEE's universal seed vaults.
