Less than a month after the release of The Elder Scrolls Online for console, creative director Paul Sage has left the game’s developer, Zenimax Online Studios. Game director Matt Firor remains on-board for the project, while Sage’s position of creative director is being filled by Rich Lambert.

He previously worked as lead content designer for The Elder Scrolls Online. He also worked on The Elder Scrolls IV: Oblivion.

“We can confirm that Paul left Zenimax Online Studios after the launch of The Elder Scrolls Online on console,” a representative said in the game’s forums. “He, along with rest of the team, are very happy with how the game is doing and we wish him the best in his future endeavors.”

Sage is leaving Zenimax to join Borderlands developer Gearbox Software, reports Eurogamer. That studio is currently working on the MOBA-like shooter Battleborn and Borderlands 3.

It is unclear which project Sage is working on.

The Elder Scrolls Online was originally released in April 2014 as a subscription-based MMORPG. In January 2015, the game transitioned to a pay-once model and was renamed Tamriel Unlimited.
