As my first contribution to this thread, I would like to make a suggestion, specifically, regarding the Chilfos idea from PaulH. When I read this faction suggestion, (due to the fact that I find the "fos" creatures more interesting than the games themselves.) I thought this was pure genius, however, this may add to the idea. Red Ice Chilfos, any person who's played OoT knows that these frozen blocks of evil were impervious to the elements and regular flame. So, it could work like this, if the chilfos took zoras domain, they would get the ice temple, along with access to this red ice, their "leader" could see this as a way to improve his troops. So, red ice chilfos would have superior armor ratings/attack than the regular ones, but would be far more expensive to train considering they are magical constructs made of magical material, (Instead of magical constructs made of regular material) Because it's fireproof, this would also negate fire arrow damage bonuses, along with removing the disadvantages of fighting in the desert/other areas (combine that with stalfos level morale, and they'd be pretty overpowered). Of course, to balance these huge improvements out, you could make it so that they're only recruitable from captured zora territory.
(Put lame ice related pun here)
(This is the winter of our disco tent) I seriously need to make this my signature.
Wow, super-fit Rauru... he's so thin he actually makes me think of his Twilight Princess counterpart, Auru.
Isn't he a bit old to wield a mace (effectively)? Either way, it's good to finally see an Hylian Sage join the fray. I should hope he has some of the msot powerful magic attacks in the game.
Honestly though, I always thought the fight between Gandalf and Saruman looked a bit silly. Kept thinking "How have their bones not snapped like dry twigs yet?"
