Square Enix and Crystal Dynamics have announced that Rhianna Pratchett, lead writer on both the Tomb Raider reboot and Rise of the Tomb Raider, is no longer working on the series.

According to the developer, she’s “off to pursue new adventures separate from the Tomb Raider franchise.” She also worked on the comics based on the series.

Here’s the full statement from the publisher:

Crystal Dynamics and Rhianna Pratchett are announcing today that Rhianna is off to pursue 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. 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 acknowledged the departure on her Twitter, saying: “So, I’m packing up my climbing axe plus a little venison jerky for the road, and bidding a fond farewell to Lara. Onwards to new adventures!”

Prior to her departure, franchise director Brian Horton left the series back in December of last year, with Ian Milham acting as the new franchise director.
