Necrolyte clan

The Necrolyte clan was a mentioned grouping of orcish necrolytes dating back before the First War. The necrolytes used the Void, as discovered by Natalie Seline.

Mentions of "Necrolytes" throughout these sources may or may not refer to the clan.

Speculation
This may be a euphemism for a more formally named clan, such as the Shadowmoon clan, who included necrolytes in its ranks. Perhaps it merely refers to the necrolyte class as a group, not unique to any clan. It is even possible that there was in fact an early clan in the Horde called the Necrolyte clan. This possibility is what is implied by Warcraft: Orcs & Humans, but later sources contradict this. If so, this clan may have later evolved into the Shadow Council, the Stormreaver clan, or a similar group loyal to Gul'dan. In Warcraft II: Tides of Darkness, the necrolytes are a subgroup within the "Warlock clans".
