That\'s right in the historical form (which is a bit borring in a game). But in a more AD&D form, there are evil palladins which are exactly the opposite like the sith in star wars.
For example, if a palladin has an aura of luck, the evil(dark) palladin has an aura of bad luck, he can inflict damage by touch and other things ...

That\'s a very interesting post but I don\'t agree with a certain amount of things.
First, your definition of a palladin. For me, he\'s someone affiliated to an organisation (church, guild or local king) and do the best he can to serve it. For example, try to avoid the darkness (or goodness for evil palladins), command army of his king during battles, ...
It\'s a sort of affiliated fighter who can have a few others capacity like healing (given by his god) but not necessary.
The other point I disagree is the necessary of a trainer. We\'ve some examples of self-learning palladins or wizards (more difficult). I think of thoses two as jobs, nothing else ... and do you know someone who do the same job all his life ?
Ok, just back a few. In planeshift, magic is everywhere. Now, magic seems very marvelous but not in this universe because it\'s something natural, like water or animals. As you can use water to produce electricity, you can use magic to make light.
If gandalf is a really fantastic character it\'s just because it\'s needed in the story (must I remember you that in lotr, no human can do magic).
But I agree that the number of wizards must be limited by a natural way, like making them not to strong or rendering the magic really long and difficult to learn.
It\'s important every job is attractive to egalize the number of each one in the game.
I hope you will answer to have a good speak on this ;-)

P.S. : I\'ve seen you\'re not putting the quests on the planeshift bible but will you put some other type of help like where to found an item, what\'s needed to smith something ? I hope not, this will destroy every attempt to enhance roleplaying.
