Death's Head tribe

The Death's Head tribe (also known simply as Death's Head) is a group of undead quilboars found in Razorfen Downs in Kalimdor. They are controlled by the Scourge, led by the lich Amnennar the Coldbringer, and were the first major Scourge-outpost on Kalimdor. They are allied with the Razorfen tribe.

Preachers of Agamaggan and the Death's Head are known as speakers and prophets. Some notable elite members include Death Speaker Jargba, Aggem Thorncurse. The current crone Charlga Razorflank is said to be officially leading it. According to Shagtusk, Chugara Razorflank surrendered Razorfen Downs to the Death's Head.

The Heads also house a giant boar, Agathelos the Raging.

After Amnennar's initial defeat, Death Speaker Blackthorn took control of the cult.

In the RPG
From Lands of Mystery:
 * Following Agamaggan's defeat, quilboar occupied the the sites of his fallen body, Razorfen Kraul and Razorfen Downs. Here the most powerful quilboar tribe in the land, the Razorfens, practice shamanistic magic and stages on rival tribes and Horde villages. Charlga Razorflank leads the Razorfens. Rumors hint that Charlga may be in negotiations with agents of the Scourge. In the Downs, the Death's Head tribe has already been turned by the undead. A powerful lich named Anmennar the Coldbringer commands the undead Razorfen Downs, and he has many powerful creatures under his control, including a massive abomination.

Origin of the Name
The name Death's Head was likely chosen after Agamaggan’s death and his children’s pledge to his legacy. The traditional capital city, Razorfen Downs, is housed through an entrance resembling a giant boar head. It is likely that when the Downs were under quilboar control, the cult was established here and named as tribute to the fallen boar god.

Creation
There appears to be some discrepancy on how exactly the Death's Head was formed.

Several quests (some removed in Cataclysm) suggest that the quilboar willingly allied themselves with the Scourge. The quest An Unholy Alliance (Classic) clearly describes how peacefully and politely this allegiance came to be, with the Scourge's ambassador asking (by letter) Charlga Razorflank for aid:

The book Compendium of Fallen Heroes, which was implemented in the game much later, gives however a completely different explanation:
 * "Tartek the Enraged. One of the most powerful abominations the Scourge has ever created. Assembled by lich Amnennar the Coldbringer to assist in setting up a base at Razorfen Downs. Tartek single-handedly felled more than 1,200 quilboar before being overcome. His sacrifice provided the corpses for Amnennar to quickly raise an undead quillboar army of his own, ultimately assembling the first major Scourge outpost on Kalimdor."

Although the versions differ heavily it is not impossible that both are the case. A possible explanation may be that Amnennar carried out the massacre in Razorfen Downs without Charlga even knowing. The Scourge, already heavily established once Amnennar finished his army, might then have planned to expand their territory through negotiating with the still living quilboars. This scenario seems to match: Alternatively, it is possible that the Scourge simply first approached the quilboar amically, in order to later turn on them and raise them all as undead minions.
 * The description given in Lands of Mystery.
 * The quests (if the quilboars' aligning and pact with the Scourge simply refers to them being a part of it, willingly or not).
 * How Ambassador Malcin could remain outside Razorfen Downs while waiting for Charlga's answer.
 * Charlga's in-game quote "Our new allies will avenge us!".
 * Mordresh Fire Eye's (a skeleton in Razorfen Downs) in-game quote "We will enslave the quilboar!".
 * How Charlga is still an Humanoid and not an Undead.
 * How Ragglesnout, a living quilboar, can be stationed in Razorfen Downs if the living quilboars (unaware of the massacre) believe the undead ones to be their friends.
 * The quest Agamaggan's Charge, if Charlga believes the undead quilboars willingly converted to undeath: "Charlga Razorflank has steered my children into darkness, driven into insanity by the Scourge." Still, if this is case, it is an odd solution to kill Charlga in order to stop the Scourge.
