Sian Jeisel was a female Devaronian Jedi Master who served the Jedi Order during the Jedi Renaissance era and the following Golden Age. A dutiful Jedi, Jeisel felt that the Order should not have gotten involved in the Clone Wars, the major conflict between the Galactic Republic and the Confederacy of Independent Systems and initially invoked her Right of Denial and refused to serve as a general. It wasn't until Master Mace Windu eventually persuaded her to return to Coruscant, that she would take up the rank of General within the Grand Army of the Republic.
