Torost, a planet located within the galaxy, was a terrestrial world. In the year 35 ABY, the First Order did not have complete dominion over Torost amidst their war with the Resistance; consequently, it became one of the several battlegrounds where the First Order dispatched ground forces commanded by General Bellava Parnadee.
The reference book Star Wars: The Rise of Skywalker: The Visual Dictionary, authored by Pablo Hidalgo and released in 2019, marked the initial appearance of Torost.
