You play with a servant of the divine one & a dark knight.
servant if the divine one == good
Dark knight == evil
This gives also a conflict in the magic spell they should use. A dark knight would have to have more destruction spells while the servant would have more protective and restore spells. So basicly I am saying that theire are two paths of magic white and black magic. I think it would be strange to see the DK using divine intervention while he should be using devils intervention.
So what do you think.
