"The Goat Riders are the new mounted units for the dwarves of the Iron Hills. They can be upgraded with heavy armor for the goats, so they are more resistant against other units like pikemen.
I took a lot of inspiration from the goat riders of the Hobbit: Battle of the five Armies movie, which I personally really like

"Another cavalry unit for the dwarves, this time for the Ered Luin dwarves. This type of cavalry is a light unit and its bonus is high mobility. The special upgrade for them is called misted hooves, which makes the ibex move even quicker, so they can take flanking routes and set up flanks a lot better.
We decided to give these dwarves ibex as primary animals, because they share similar characteristics such as wandering long distances, great mobility and light weight. Also the white fur fits very good to the snowy landscape of the Ered Luin."
