THE STORY
After being reforged, Lord-Relictor Ramus of the Hallowed Knights is sent by Sigmar to capture the betrayer, Mannfred von Carstein. The quest brings Ramus to the Carthic Oldwoods of Ghur where he comes to the aid of the Astral Templars against a massive ogor horde. Victorious, but at great cost, Ramus discovers Mannfred is finally close at hand. Only with the help of the Astral Templars will the Lord-Relictor catch his quarry, but there are deadlier things in the woods than ogors, a fact the Stormcast Eternals soon discover.
Well can't wait to listen to it I will give my thoughts on it later.

Riight my thoughts after the first listen you get a few lines from sigmar that he wants mannfred delivered to him in sliver chains. We see that nagash's curse on vampires is still in effect and we are starting to see mortal auxiliaries and the building of settlements it makes sense considering the warbeast novel its quite a throw away line but something I took keen interest in.
Warbeast spoiler
Now our first introduction to the Astral Templars they were put in charge of the colonies by sigmar and well... Astral Templars = space wolves pretty much and they hold memories sacred and tell stories of each brother when they die because they don't want to forget anything. Plus I think they are using this audio drama to introduce the orcs aka orruks.
Considering Mannfred was afraid of something, Mannfred noted to Ramus that they should concern themselves with that unknown threat than him of course Ramus did not care what he had to say considering the events of the previous Volume.
I feel it was a pretty good continuation from the previous volume of the audio drama. Oh and Ogres are
OP.
