Keepers of Time Tips

You can gain reputation with the Keepers of Time by running the two instances in the Caverns of Time and completing one-time quests there. You can gain reputation up until exalted by doing runs of Old Hillsbrad and Black Morass. Black Morass gives a little more reputation per run and is generally easier to find a group for. The one-time quests for the events in each instance yield substantial chunks of reputation.
