Pegasus aerie

Pegasus Aerie is a Bretonnia military recruitment building in Total War: Warhammer. The highly-prized pegasi of the Grey Mountains are kept in opulent 'sky-stables' known as aeries.

Background
Most Pegasus Knights hail from around the border city of Parravon. Here, there is a whole cottage industry built around trekking into the Grey Mountains, hunting wild pegasi - or their foals - and then rearing or training them to be suitable battlefield mounts for Knights of the Realm.
