The introductory sequences flash through space and time to Nox, where Hecubah is casting a spell. It seems Hecubah is in search of a particularly powerful orb with which she can take over the world of Nox, and as it happens, said orb happens to be resting on the television in your trailer currently blasting the latest wrestling match. Hecubah finishes her spell-casting but rather than summoning the orb, she summons the television and you. This of course, leads you to the discovery that you are the only person that can save Nox from the evil Hecubah. Although I'm not sure it was designed precisely for this reason, they end up being a type of difficulty setting.
Warriors are strong, can use a wide variety of melee weaponry, and bash the hell out of everything.
Conjurors are a sort of hybrid who can use a limited number weapons, but primarily rely on their ability to control other creatures to do their bashing. Wizards rely almost entirely on their repertoire of spells and only have staffs available for bonking things on the head. Each character starts in a different place and often have different goals. Aside from giving creatures a headache, bashing is important because you get much of your loot from barrels and boxes that you have to break open. I've found that if you whack them really hard, you can get the loot to fly pretty far.
