At most magic or potion making schools there is usually a small zoo so that they can take claws, teeth, hairs, horns, and other potion making suplies from them when needed.
Boldoriesh was built by the wizard Zarona long ago. The ground he built it on was dry and cracked with huge trenches and canyons all over. Zarona had his men drop metal, wood, rope, and other building materials down into the cracks and trenches, then he just magicked it up from the ground.
Zynara has a roof. The sun, moon, stars, and clouds are under the roof. The rain and snow and such come out of the clouds. The cloud goblins control it though.
There is a sea stretching out from the edge of the realm of King Quidam. It sticks far out, away from the edge of Zynara.
