The main hub in Reign of Ysera is an instanced map serving as a Garrison. This place will be the only more or less safe place inside of the Emerald Nightmare and it will be used to launch all the attacks on the Nightmare.
Instead of the reduced Garrison in Draenor this is a bigger instanced zone where no other players will be seen, however it holds both Alliance and Horde forces as well as Neutral allies.

The dragon isles are one of the high level zones in Reign of Ysera.
