Whenever a new group of Survivor contestants enters the fray to compete for the million-dollar prize, they’re standing on the shoulders of hundreds of people who have played before them. For its 39th season, the hit reality show is embracing that in bringing back two legends of the game to educate the latest crop of castaways. Twenty new players will get a chance to learn from the best on Survivor: Island of the Idols, premiering on CBS on September 25 at 8 p.m.

Host and executive producer Jeff Probst has branded this season as “Survivor boot camp.” Infamous players “Boston” Rob Mariano and Sandra Diaz-Twine will live out on the titular island, receiving a visitor every episode. The duo will teach that person an important lesson applicable to Survivor that they can use to better their position. They then have the opportunity to test their newly-learned skills for a chance at an advantage, or a penalty that might get them discharged from the tribal troops. Outside of Rob and Sandra, the cast this season contains a unique cross-section of individuals, including the series’ first-ever Indian-American and Canadian contestants.
