Argus Wake

The Argus Wake are a mysterious group allied to the Syndicate in Alterac. According to Thrall, they are members of the Shadow Council.

The Argus Wake has made use of bloodstone, primarily in the form of Bloodstone Amulets and the Befouled Bloodstone Orb. The amulets were then distributed among the Syndicate.

Nearly all the information about this group comes from a letter, which was found by adventurers of the Alliance, and translated by Prospector Stormpike.

Unnamed

 * Argus Shadow Mages

Trivia

 * The group's name may have originated in Bloodlines, a scrapped game by Blizzard Entertainment. Concept art for the game includes a man with an eye icon on his forehead; beside him, the icon is drawn on its own and labeled "The Argus Wake".

Speculation
Judging from the last lines of the letter, it can be implied that the Argus Wake is one of the more powerful splinter cults of the Shadow Council, reporting directly to the higher powers of the Burning Legion. It is unknown who or what the "Third Host" is, however if the Argus Wake are servants of the Burning Legion, it is possible this note refers to a third host for Sargeras, the first two being Aegwynn and Medivh.

In other sources of Warcraft lore, a "host" is also the term used for the main body of an army. So it is also likely that the Third Host is the next invading force to be sent by the Burning Legion (the first having been sent during the War of the Ancients, and the second during the Third War).

The name Argus Wake is likely connected to the eredar homeworld of Argus.

The bloodstone used by the Argus Wake may result from the stealing of a Bloodstone Artifact sent by Warden Belamoore to Dalaran.
