From the World of Warcraft European community website: "In Zangarmarsh, you can earn Honor Hold (Alliance) and Thrallmar (Horde) tokens by slaying enemy players near the PvP capture points. The PvP objectives in Zangarmarsh are comprised of the Twin Spire Ruins. You will gain a token for each enemy player you defeat in the vicinity of the ruins."
