----------
Suramar City is still intact thanks to a defensive spell from the city's mages. They harnessed the power of the Nightwell, keeping it up for 10,000 years.
The elves became dependent on the energies of the well, relying on it for living energy.
The elves in the city are a new type, The Nightborne.
The gates of the city were opened to the Legion. The city is kept in darkness.
Crimes are punished by exile of the city. Physical withdrawal makes them into The Nightfallen.
If a Nightfallen can't get arcane sustenance, they become permanently Withered.
Ancient Night Elves are arcane based, not nature based.
Suramar City is one of the most ambitious projects the team has ever done. A giant playable Night Elf metropolis.
