For the main 'good guy' I want him to be fully adapted to the jungle because I want the knights to be the most powerful creatures across all terrains but the main good guy's native place is the jungle so he would be the most suited to living and fighting in the trees.

   

With magic being around everywhere I think the plants and trees that make up the surroundings would have to be a lot tougher than plants around today. 

I want to have a few creatures that aid the knights, like horses but more fantasy, more suited to the surroundings. I think something like a big jungle cat would be a good starting point. 

I think some sort of armour would be needed to be able to survive in the harsh surroundings.

With the main 'bad guy' being good initially I want him to give off a weird, I don't trust you feel. To try and portray this I want to give him creepy features so even if he was a 'good guy' you still wouldn't totally trust him.

 A common occurrence in sorcerers seems to be hoods, big shoulder pads and long coats. however, though these guys look a little untrustworthy, this guy is a  powerful sorcerer he would transform himself to be a little better suited to his surroundings. With the temple being in the middle of nature, I think it would be cool if he was centaur or something.

I like the idea of the bottom half of him to be spider or crab or anything that scurries because i know a lot of people, including my self, get freaked out by things like that so I think that something like that will give the desired off putting look i am looking for.

I have found quite a lot of examples of half horse but i am struggling to find much of anything else, I am going to do a few animation tests of a spider walking to give myself a clearer view of what it is i want him to look like.
