The Trannisa Conglomerate's headquarters were on the Uta continent. It is a small continent in a portion of the realm where most people never ventured.
This portion of the realm was safe to some extent but it was very close to the nesting grounds of strange creatures called stark hawks.
These birds were actually vital to the realm. They were a large source of wind energy. This energy became wind and/or lightning magics and could be used to power machinery in its energy form.
To fly, their wings were essentially wind generators. They had learned to use wind magic to help them in flight especially when hunting. So when they flew they looked like living airplanes. Their wings stayed out to full wing span (they never flapped them) and they moved through the air absorbing rainbow magic and exuding wind energy.
