The ruined city of Oldport, destroyed nearly 200 years ago during a violent raid from the sea. During the day, a desolated skeleton of what once a thriving port city. During the night, magical splendor causes the city to regain its former glory and the dead rise to continue their lives.
The ruin that birthed a society; the Life and Times of a city in the throes of death.
11 great statues of lost gods being chipped away by the condemned.
Perhaps those that practice elemental magic begin to take on characteristics associated with their chosen element. For instance, an earth elementalist might be prone to agoraphobia, while air and possibly fire elementalists might have problems with claustrophobia. Water elementalists might always seek the path of least resistance. A fire elementalist might have a cat's opinion of water. This could also apply to physical differences. Fire elementalists might have a freakishly high metabolism and a permanently high body temperature. Water elementalists would probably never get dehydrated, but might slow down a lot when it's cold. Etc, etc.
