I can imagine that having a full grown rancor in the barn as a Creature Handler, might be presenting a funny situation of not being able to see its head. Let alone that three of those beasts in there would feel crowded real fast. Which makes me kind of thinking about an outdoors area to let them roam around. And this then kind of makes my mind wonder to a building I saw at Legends; the ranch.
I like the kind of building with the outdoors space where a number of creatures/beasts could wander around. And to be clear; I'm talking about the building, not the other stuff that comes with it.
