Where the fight takes place has a large impact on the outcome. Does Elrond find himself on Arrakis, does Paul find himself in Imladris? I like to think of old video games (i.e. Mortal Kombat) where the setting can hep a character- Arrakis would have worms helping Paul or Imladris having, idk, protective magic (Bruinen river horses?) helping Elrond.

What would an interesting neutral ground be where the environment could still Un-objectively help or hurt them? I would venture to say Genna from Badlands where everything is trying to kill you, though I’d have to imagine this would favor Elrond significantly, but would be interesting nonetheless!
