Crystal Dynamics has announced that Rhianna Pratchett, the lead writer of the 2013 Tomb Raider reboot and the 2015 sequel Rise of the Tomb Raider, has moved on to "new adventures separate from the Tomb Raider franchise."

"Rhianna was instrumental in helping us find Lara's voice in the 2013 origin story, and through Rise of the Tomb Raider she shaped Lara into the evolving heroine we know today," developer Crystal Dynamics wrote. "The entire team thanks Rhianna for her dedication and tireless efforts on the games. Please join us in wishing Rhianna the absolute best in her next adventure."

Pratchett tweeted similarly good vibes, writing, "I want to thank the @CrystalDynamics team for their dedication esp. @jstafford @josefkstories & @noahmhughes. Guys, it's been emotional. But, I like to think we did some good things. Maybe shifted the gaming landscape a wee bit. And that feels damn good."

I also want to thank TR's terrific fan community. You really are the best in the world. Constantly helping me remember why I do this job.January 3, 2017

It sounds like an amicable parting of ways, but still has to represent a loss for the series. The reboot was strongly praised for turning Lara Croft into a real character, and Rise of the Tomb Raider was selected as the winner of the 2016 Videogame Writing Award. It wasn't a solo win—lead narrative designer John Stafford, narrative designer Cameron Suey, and additional writer Philip Gelatt also got their names engraved on the trophy—but as the lead writer, her voice was far and away the one heard the loudest. Those are some big shoes to fill.
