The Rift is a Persistent World (PW) module, built in Neverwinter Night's Aurora Toolset and designed for a large number of players. The module is inspired from elements of some of the best RPGs of all time including: The Legend of Zelda, the Elder Scrolls, Secret of Mana, The Lord of the Rings, and Neverwinter Nights. The initial idea was inspired by the movie Timeline.
Looks good, especially the skybox.
