A low-to-mid level campaign, in which the least of the enemies wishes to eat you, and the greatest might step on you. Dinosaurs run rampant on Isla Sorna, and there are few safe places. On the plus side, players coming to Isla Sorna have the Winged Velociraptor pack to help them, which tends to give an edge against enemies.
The only playable race that comes from Isla Sorna is Winged Raptors. If you are creating a raptor, treat them as normal characters. Outsiders coming to the island should be level 6 or higher.
Winged Raptors can be Chaotic, Neutral, or Lawful, but only Sorna Shaman Raptors can be Good or Evil. All other must be neutral in that way.
