Strength of the Earth  

'At least our dwarf-friend is no longer scattered in pieces among the wretched Orc-hordes. We have restored a little of his stolen honour. Alas for this poor fellow, and the wretched errand that brought him to his doom.

'I wonder if there was anything behind this attack. Orc savagery is not surprising in any circumstance, but the taking of trophies is not something average Orcs do. I wonder what force drives this particular horde, and who commands them.

'We shall find out Name. Take these pieces to my friend, Frosti Groundshaker, in Thorin's Hall by the auctioneers south of the throne. He is very scholaryly, and enjoys solving puzzles such as this.'

Having discovered the signs of foul play among the nearby Orc-horde, Armbeald has asked you to seek out Frosti Groundshaker, a wise fellow who is learned in many lores, to discover more about White Hand Orcs and their behaviour.
