Changes

During the [[Horus Heresy]], Armarok was serves a the warp-entity known as the [[Erlking]]. The erlking Erlking and his followers, Armarok included, appeared as hulking bipedal wolves who spoke in [[juvjk]], the ancient hearth language of [[Fenris]]. In preparation for his attack on Horus, Leman Russ' journeyed into the [[Warp|Underverse]] seeking knowledge on how to defeat the once-[[Luna Wolves]] [[primarch]].{{Fn|2}}

Upon Russ's entrance into the Underverse, he appeared in a featureless snowy plane at night. The night sky's stars shifted if focussed on for too long and the depth of the snow varied from knee deep to chest-height for the primarch. Russ spied a large black quadrupedal wolf with gleaming yellow eyes on the horizon, at a barely visible distance. Russ pursued the wolf, barely keeping pace, blundering through snowbanks, never gaining or losing distance. After many hours, its revealed the destination was the hall of the [[Erlking]], the lord of wights and of the [[alvar]], the god of the [[nettagangr]]. Amarok would shift to his bipedal half-wolf form as he entered his lord's hall, [[Muspjall]], the hall of those who die deaths that serve no one. The half-cooked corpses of cowards and those slain by age are served in feasts at their tables. Russ would enter the hall not long after Amarok arrived, having stalked the wolf all the way there.{{Fn|2}}
