Anomalies appear during and after The G-Nome Project. During the quest, 15 anomalies must be sealed for Aubury, who attempts to use the energy rift to bring the clockwork gnome to life. During and after the quest, they spawn occasionally when channelling the energy rift. Sealing them grants Runecrafting or Summoning experience, depending on the configuration of the rift. At level 99 in the respective skill, 122.8 experience is gained from sealing one.
