The human domain, Vermilion Kingdom, and the Royal Capital...
In the Royal Capital, the Royal Island was recognized as the most luxurious and safest district in the entire kingdom, and one of the most secure in the entire human domain. This reputation was thanks to the powerful Dwarven-altered flying carriages.
Each of these carriages possessed an inbuilt magical cannon, and although it wasn't as destructive as nuclear weapons back on Earth, the sheer firepower was capable of obliterating Awakened beings ranging from Level 50 to 100 with a single blast. About 20 of these destructive carriages patrolled the airspace of the island.
Rumors claimed that the carriages had cost a fortune—enough that, if given to a poor man, it could feed his family for fifteen generations.
