Eternal Palace

The Palace has a number of dry rooms where water was removed magically.  These rooms are typically serve archival purposes, however several also allow for the safe storage of other items meant for land.  There is also a specialized pressure chamber built into the palace that is used in the training of the Royal Guard, as it would be dangerous to simply take someone to the surface who had never experienced the lower pressures before.  Instead, carefully, they can be acclimated over time to be able to accompany Queen Anja and her wife as needed.  (Additionally, the pressure chamber is used to help retain acclimation for those who have managed acclimated to the surface, as without regular exposure to the lower pressures, they may lose the ability to stand it).
