Lariss Pavillion is a large outdoor night elf style building in Feralas just north of Camp Mojache. The nearby dryads that are usually peaceful have been corrupted by the Nightmare and now attack anyone.
The Pavilion is home to a mysterious man named Azj'Tordin. Apparently a Highborne who disagreed with Prince Tortheldrin, he left Dire Maul via means of a backdoor located at the bottom of the Pavilion, but not before an imp by the name of Pusillin stole his book of incantations.
An orc, Xerash Fireblade, can also be found here.
