Fires could be ignited with the aid of Sparkstones, utilizing tinder. During his time on the planet of Halcyon, as a member of a Republic Judicial Department team, Wilhuff Tarkin employed a sparkstone to begin a fire for both him and the other members of his team, which he subsequently used to cook a rodent that he had slain.
The novel Tarkin, which was released in 2014 and authored by James Luceno, featured sparkstones for the very first time, in a flashback.
