Undying Army

The Undying Army is a reputation faction in Maldraxxus and the faction associated with the Necrolord Covenant. It is the loyal army of the Primus, typically consisting of the combined might of all 5 of the Maldraxxi Houses. However, when the Primus disappeared, several barons and margraves of the Five Houses instead swore loyalty to the Jailer. Over the course of the Maldraxxus storyline, it is shown that the Houses of Constructs and Rituals have already fallen under the Jailer's influence, while the House of the Chosen is overthrown and the Houses of Eyes and Plagues were severely crippled.

Consequently, it is only those loyal to the Primus' mission to defend the Shadowlands who constitute the Undying Army faction in-game. The faction consists of the outcast members of all 5 houses who refuse to follow the Jailer, and instead unite under both Baroness Draka and an adventurer who wields the Blade of the Primus. They fight to unite Maldraxxus once again and to defend the Shadowlands as a whole from all who would threaten it.

Description
''Long ago, the Primus established the five houses of Maldraxxus to build the ultimate fighting force. Through might, cleverness, and guile, this unyielding armada is pledged to defend the Shadowlands against all threats.''

''These five houses embody the might of Maldraxxus. Armies vie for dominance over them in unending conflict. The ill-fitting are replaced by the better-suited. The only true constant of Maldraxxus is that change is driven by strength.''
