The Shadowmoon clan, also known as Shadow Moon clan, was led by the orc shaman Ner'zhul, and was the most powerful clan on Draenor prior to the world's destruction. Named for the Shadowmoon Valley in which it was based, the clan was very heavily influenced by shamanistic traditions, like all orcish clans at that time. Their way of shamanism is different than the other orcish shamans in that they use void magic instead of the water, fire, earth and air. Although the Shadowmoon clan practiced traditional orc shamanism, their leader, Ner'zhul practiced a much darker version of shamanism. His own shamanic practices were heavily influenced by Warlock magic, a result of Ner'zhul's trafficking with Kil'jaeden, a demon of immense power.
