Menagerie is a Empire military recruitment building in Total War: Warhammer. A place to hold the many dangerous and exotic beasts that would otherwise dwell in the wilderness.
Background
The zoos and menageries of the Empire are rare institutions. Only the largest and prosperous of cities have them, the most famous example being the Imperial Zoo in Altdorf - home to a Dragon, many Pegasi and, of course, Deathclaw � the personal mount of Karl Franz.
