Kalla's arrival was loud like thunder and fast like lightning.
"Rise my legions!" A command from her voice and two taps on the ground was all that it took for the undead army buried under the mining town to awake and fight for their master.
The bulk of her force was made up of Skeletal Knights, a class of undead that was not only physically superior to normal skeletons, but also could be imparted skills and techniques their maker was capable of executing.
Their strongest point was the ability to wield and use equipment properly. The academy had provided a huge number of enchanted weapons and armors, making them a force to be reckoned with.
Kalla's elite forces were the Wights, black hooded figures molded out of darkness magic and hatred. They would either fly or float mid air. Aside from their hands and heads, they had no body. Whatever they touched, it would wither and die.
