In the latest Everquest producer's letter, Thom Terrazas goes into more details about the recently announced 17th expansion, House of Thule. The letter gives a few more details about the new features coming with HoT: Player housing, trophy system, a bigger inventory, a higher level cap, and spells. There is even a snippet about the House of Thule beta:
HoT Beta registration launched while we were at Fan Faire and Beta Launched on August 9th. So if you want to come and check out these features before everyone else, head to the Beta Registration Page and sign up. We’ll try to accommodate as many people as possible, but be sure to sign the NDA and send it back or we’ll be forced to use an existing dwarf again….And that’s a pain cause they always take twice as long to finish anything. Pfft!
