The Mad Years

The Mad Years is the name of the neverending crusades undertaken by the Mourning Wardens Space Marine Chapter during the tumultuous first century of the 42nd Millennium.

Background
The first century of M42 was a time of trials like never before for the Mourning Wardens, who felt besieged on all side, xenos, Chaos forces and even simple secessionists trying to make use of the turmoil to carve out their own petty realms. Thankfully, the Wardens received over 350 Primaris, sent directly from the vaults where Archmagos Belisarius Cawl had kept them for ten thousands years. Thanks to them, the Mourning Wardens managed to not only hold their own but to crush any and all their foes, even going as far as to bringing Imperial Compliance to dens of traitors and pirates which had never been freed from the yoke of the Long Night. But the Brothers felt that they failed to sufficiently expand the borders of the Empire in this time of madness. Furthermore, tensions grew heavy between some original Astartes and the newly added Primaris, which made this century all the more difficult to endure.
