Wyrmcult

The Wyrmcult is a group of humans, orcs, broken, and draenei that seem to worship the surviving members of the black dragonflight, most of which were killed off by the gronn after the destruction of Draenor. Their coven is located in Raven's Wood in the western part of Blade's Edge Mountains. The Wyrmcult fells trees and hunts animals in the Ruuan Weald, much to the dislike of the druids in Evergrove — whom the Wyrmcultists are unwilling to negotiate with.

History
The Wyrmcult cultists were keeping themselves in Blackwing Coven, but with the arrival of the Cenarion Expedition they are encroaching upon Evergrove.

Tree Warden Chawn is looking forward to negotiate with the the overseer Nuaar, because the wyrmcult is making difficult the healing of Blade's Edge Mountains. Samia Inkling and adventurers helped Tree Warden Chawn, but the cultists rejected the negotiations because they believe that the Cenarion Expedition doesn't own the mountain and doesn't have the authority to tell them what to do as they are "free people". Seeing this Chawn, is sending adventurers to kill the hewers that are cutting trees.

Samia Inkling is investigating the Blackwing Coven and is trying to get Black Dragon Whelps with the own cultists' nets, carried by their poachers.

In Wyrmskull Bridge and Wyrmskull Tunnel Watcher Moonshade is leading the defense to stop the wyrmcult from leaving Blackwing Coven and from doing something dangerous. He and his wardens are being hard pressed by the cultists, because of the number of troops, so he planned to defeat their leader Draaca Longtail.

Overseer Nuaar and Kolphis Darkscale were going to meet to discuss their plans, which consisted in attacking the Cenarion Expedition, but after Tree Warden Chawn, knew this he began sending adventurers to defeat the leader Maxnar the Ashmaw.

It is unknown what their end goals are, but they appear to be breeding many black dragon whelps.

Speculation
They breed Black Dragon Whelps that Samia Inkling wants to get. As she is sent by Sabellian, a black dragon, and her final quote is "This looks like a fine brood of blackwhelps to make a start with. Examining them, that is.", it is probable that Sabellian wants the whelps for himself.

They may be working to be worthy of becoming black dragonkin or black dragonspawns. If that is their goal, Maxnar was seemingly successful in becoming a drakonid (or he was born as one), along with the Wyrmcult Blessed.
