Rephaim

The Rephaim are the enormous shades of ancient dead, remembered as departed kings, warriors, or giants whose presence remains beneath later history. They rise without flesh but retain the stature and authority of their former age. One Rephaite shade answers grave robbery, false kingship, or an oath sworn upon a dynasty that no longer exists.

Dead King's Command: one creature within 60 ft makes a Mind save or kneels, drops one held object, and cannot attack until the end of its next turn.

Name the Ended Kingdom: proof that the Rephaite's rule truly ended removes its DR and grants another save against Dead King's Command. Returning grave goods may end the encounter.
