Harth Stonebrew

Harth Stonebrew, better known simply as the Innkeeper, is a dwarven innkeeper. He acts as a guide for the Hearthstone board game and is the owner of the inn in which the game takes place.

Harth has a pet mouse named Sarge.

Canonicity
The canonicity of the game of Hearthstone is that of flavor lore. It is a game developed in inns and exists within the Warcraft universe, but may not accurately represent things as they really are.

Whether or not Harth himself and other Hearthstone-specific characters (such as Nexus-Champion Saraad or Skycap'n Kragg) are canon in the Warcraft universe has not yet been determined.

Trivia

 * His appearance is based on the dwarf from the The Perfect Stout TCG card (probably Rejold Barleybrew).
 * Harth has been listed as a possible character for inclusion in Heroes of the Storm.
