The Lost Valley is located beneath the catacombs under the Monastery. The Lost Valley is styled after Jurassic Park by Vince, Rex, and Questor (hope I got the abbreviations right), and is recommended by the area list for levels 70 - 99. This is a pretty good estimate, although some level 70 chars will defiantly have a hard time there. There are currently no level restrictions imposed by the immortals, so anyone can visit.

Most of the mobs are non-aggressive, and most of the ones are are aggressive, cannot see invisible. The aggressive mobs are Trex, Velicoraptors, Allosaraus, Saber-Toothed Tiger, Giant Crocodile, and Tylosaraus. All but Trex and the giant crocodiles are sentinel, and only Saber-toothed Tiger, velicoraptors, and Tylosaraus can see invisible.

Interesting items found here include the Trex Crown and Raptor Rope necklaces.

The Lost Valley is a good place for characters to gain their last 15 levels or so, but there number of mobs is relatively limited, so if there are more than a 2 groups there, you would be better off seeking experience elsewhere.

Included are both Viewable and Printable (pdf) version of the map. The printed version will cover 2 pages in landscape format.
