A dwarf approached me today. Apparently he had heard of my work and wished for me to use my abilities against a smith named Doric.

I cared little for the details, yet he seemed set on telling me all about his situation. Feigning interest, I smiled, nodded, and laughed, as least until he was happy to hand over the money I asked for.

His proposition allows me a chance to experiment with a new spell. There is a cavern within the Dwarven Mine; home to creatures of rock. I have spent months studying these brutes and believe I can use their life essence to animate similar creatures outside of the cavern.

My spell will allow them to lay in wait until someone disturbs them – then they will attack! I shall see then how powerful my magic is.
