Randomly Roll What Beasts Do & Where In Seconds

1. Stable - Mountkeep: rideable creatures in water, air or land - or used to propel an object like carriage-chariot-wagon.
2. Owlery - Falconry - Aviary - Roost: Creatures deliver messages - oft stealthy, clever & small.
3. Zoo - Live Menagerie - Showcase: Creatures meant for modelling, display, curiosity & interest. These creatures are not harmed physically, may double down on mental abuse.
4. Monster Tank - Cage o' Rage - Moatmonster - 'Beyond Here Be Dragons': Monster kept and fed for sole purpose of being a bully, menace and threat to anyone / everyone. Shows owner's power & prestige.
5. Breedery - Puppymill: animals sold for profit and also any other category. Breeders of both genders are often pampered on all levels in hopes for more young / litters.
