Tar Lords are tar beasts found around the Lakkari Tar Pits in Un'Goro Crater.
A Tar Lord in Hearthstone
The Tar Lord appears as a common card for the Warrior class in the Journey to Un'Goro expansion for Hearthstone. Its flavor text reads: "Tar Lord, man... legendary monster? Aw, forget it."
- Hearthstone's tar beasts, including the Tar Lord, are depicted as elementals made of living tar rather than the bog beast-like creatures they are represented as in World of Warcraft.
