Bethesda has announced a new expansion for The Elder Scrolls: Legends.

The battling trading-card game will get a new expansion inspired by none other than Sheogorath, the Daedric Prince of Madness.

While details are scant, here’s a quick blurb on the new content:

You broke the chains of captivity and saved the Empire as The Forgotten Hero. You uncovered a dastardly conspiracy in The Fall of The Dark Brotherhood. You’ve uncovered the lost artifacts of Sotha Sil in the Return to Clockwork City. Now, The Elder Scrolls: Legends’ next adventure sets sights somewhere beyond the comprehension of mere mortals in the Isle of Madness!

Announced at QuakeCon 2018, Isle of Madness is a story expansion for The Elder Scrolls: Legends inspired by none other than Sheogorath, the Daedric Prince of Madness. Wabbajack in hand, his brand of unpredictability tinges not just the quests you’ll encounter, but also the cards you earn for your Collection!

As for exactly how Isle of Madness will wreak chaos in The Elder Scrolls: Legends, you’ll just have to wait to learn more. Fret not, as Sheogorath knows the value of patience – how else do you get a fine age going on the cheese he enjoys so very much?

The Elder Scrolls: Legends is currently available for Windows PC, Mac, iOS, and Android. A console launch for PlayStation 4, Xbox One, and Nintendo Switch is planned for this year.
