You can now test out your Valyrian skills at Shake Shack -- er, Rholītso Rhakion.

The Dragonglass Shake (Zīrtom Perzomy Rholītsos) is "a prime example of the Wall to Table movement"(!), according to the Shake Shack press team, and is "frozen with packed snow harvested beyond the Wall and hand churned by members of the Night's Watch. Final prep occurs in Winterfell, where the shake is topped with shards of Dragonglass imported from the caves of Dragonstone."

In English? The new shake is mint and white chocolate custard topped with shards of Dragonglass, er -- toffee.

The special edition shake will set you back $6.59, a dollar and change more than the regular shake price of $5.29.

At select locations, some lucky wildlings can feast on the $7.99 Dracarys Burger (Drakaro Parkliapos), a double cheeseburger topped with bacon and the chain's signature spicy Shack Sauce. Austinites will have to travel to the Uptown Dallas or Montrose Houston locations for a taste.

The secret menu is available April 12 through May 19, the date of the series finale.
