Drûzhag The Beastcaller is a GW-invented character that is a great addition to an army that includes beasts of Mirkwood (spiders, bats, wargs, etc.).  As such I really wanted to include it in my Dol Guldur force, but the model just never got my interest.  It is too much "fantasy" as GW often runs back to its Warhammer / 40K roots when creating something of their own. 

My solution was to make my own.  I wanted to start with an Orc that offered both a mounted and on-foot version of the model and had a dynamic pose.  The one I went with was Sharku, captain of the Warg Riders of Isengard.  I will eventually get a replacement for him (or continue to use my generic captains leading my Warg Riders), but this model was a great foundation.

Just swapping the knife for a spear (Orc Shamans all have spears) made a big difference in breaking the impression of Sharku, but to give it the "Beastcaller" theme I needed more.  My option was to give him a "cloak" made from the hide of a Giant Spider. 

I am VERY happy with the concept, but not so much the execution.  I was still pretty new to sculpting when I did this one. I think when time allows I will dislodge the current spider hide and replace it with something more "realistic" looking.
