Sarkhan Vol travels 1000 years back in time, to change the moment that sealed Tarkir's fate: the battle between Nicol Bolas and Ugin, the demise of the latter and all dragons of Tarkir (Crux of Fate). The clans still exist back in the time; they are not fighting each other but are constantly fending off the legion hordes of dragons that are terrorizing their world. Sarkhan meets khans of the past, like Yasova Dragonclaw. The history of Tarkir is rewritten.
At the Fate Reforged prerelease on January 17/18, 2015, players choose their clan. While they complete three achievements, they follow in Sarkhan's footsteps to attempt to alter fate; they get to "Heal Ugin" and "Gain a glimpse of the future". The latter comes in the form of a special "Ugin's Fate" booster pack containing two alternate art cards that show how the world has changed in the new timeline, a token and a basic land card. There's a pool of 40 alternate art cards with a holo foil stamp (mainly from Khans of Tarkir, a few from Fate Reforged, one mythic), the main change in the art being that there are dragons now. In addition, the basic lands also have alternate art, showing off Tarkir of the past.
