I don't see any later editions of Talislanta that have Sarista in the title.Sarista back cover blurb wrote:SARISTA
Immerse your PCs in one of Talislanta's lushest cultures with Sarista, the first sourcemodule for Talislanta! As a sourcemodule, Sarista provides both detailed background information on the Sarista and a short adventure that lets you use some of that material right away. Details on Sarista customs, skills, equipment, and magic add flavor to this colorful race, while information on the landscape and creatures of Silvanus fleshes out the Sarista homeland. A few special NPCs and a sample Sarista clan provide inspiration for your own adventures, while the short adventure included sends your PCs to investigate possible Tanasian activity in Silvanus. Whether your party is visiting the Western Lands or being visited by a Sarista caravan, you'll find plenty of good ideas in Sarista.
Is Tal 3e the only edition that had a book dedicated to Sarista?
(I didn't see any other books that had "Sarista" in the title, but I'm not sure if Sarista is in a wider region that was covered by a book with Sarista content.)
Are there any later books with a Sarista theme?
