Just had a vision of heavily armored dwarves defying gravity a la various kinds of goats & sheep.The Swedish RPG Eon has dwarves with a very keen sense of balance. The upside is that it allows them to navigate relatively narrow ledges underground without much problem, but the downside is extreme susceptibility to motion sickness.
Imagine the horror of their enemies, navigating through passageways and caves towards a Dwarven settlement, when out of the darkness above, they hear “DEATH FROM ABOVE” in Dwarven!
