Strange Eons: Adventures on Tethys

Well, I am finally going to run a DnD campaign in my homebrew setting of Tethys. Its a big world, full of danger and adventure, but we need to start of small(ish). As stated before, Tethys is the far-future planet Venus, brought to life by the efforts of mankind. Mankind has lost sight of his history, and now lives a primitive existence on the now-vibrant planet.
MAP: The map above is still in the early stages, and will be detailed in the future. Its a big world, with lots of places to explore.

Gaming Details
Some things need covering...

Races: Humans are preferred, though some Template races will be allowed.

Character Level: As life is quite hard on Tethys, all characters will begin at 3rd level. This is largely due to the daily struggles of the setting causing most folks to be tougher and more adventurous. NPCs will also start at 3rd level due to the same reasoning.

Class: All in the D&D 3E Players Handbook. Though the Paladin will be extremely rare, and the Bard a bad choice away from the larger city-states.

Wizards: Powerful Wizards are considered nobles merely by the fact of their magical might. It should be noted that Wizards dont like to share their power, and will keep an eye out for energetic up-and-coming Wizards and Sorcerers. Assassins can make a tidy living just bumping off young mages.

Mounts: Horses are not often used as mounts on Tethys, as they are considered irresistably tasty by many carnosaurs. Donkeys and the smaller sort of horse (ponies and light horses) are about all a person can get. As mounts, tamed and trained dinosaurs such as the
Camptosaurus (treat as a heavy horse in price and carrying capacity), Plateosaurus and
Trachodon (both treated as Elephants in price and carrying capacity) and fairly widespread. Carnosaurs make terrible mounts, but the smaller (and smarter) sort can be trained as pets.

Dinosaur Armor: Leather and Hide armor is the most common kind of armor. Armor or shields made from the more armored sort of dinosaur (such as an Anklyosaurus) may be used to produce armor or shields of Masterwork quality.
One armored dinosaur produces enough hide for a single suit of masterwork hide armor for a creature one size category smaller than the dinosaur. By selecting only choice plates and bits of hide, an armorsmith can produce one suit of masterwork banded mail for a creature two sizes smaller, one suit of masterwork half-plate for a creature three sizes smaller, or one masterwork breastplate or suit of full plate for a creature four sizes smaller. In each case, enough hide is available to produce a small or large masterwork shield in addition to the armor, provided that the dinosaur is Large or larger. Armored Dino Hide offers 10 hit points per inch of thickness and hardness 10. Also, Druids may wear such armor without penalty, as it is not made of metal.

Fun Stuff!
Below is a memorable clip from the movie One Million BC! This movie enchanted me as a boy. Dinosaurs, lots of action and hot barbarian women. What more does a growing lad need?

In Tethys Terms: This scene shows two members of a remote Barbarian tribe encountering a rogue (herdless) Triceratops and a hunting Ceratosaurus. Possibly in a highlands region of the Thunder Range. A bad place to be cought to be sure.
