so...I know "Magic" has been a debate for a long time, always, due to tolkien not really emphasizing much on it.
However, "Magic", as we tend to think of it, isn't how it is in the lore-world. It seems that all magic used by people aside from the wizards, ((the "magic" or the elves, dwarves, objects, etc.)) are based on a deeper understanding of nature. That words and the will to use them have power.
I believe there are points that...well, yes, the istari are the only WIZARDS that exist. There are probably many Conjurers among the other races. Dwarves with their runes and words of powers, elves, I'm sure the race of men also has conjurers. Now conjurers wouldn't be able to anything major, small magical feats, maybe some form of communication to animals, possibly the ability to slightly enchant something, skills based on words/alchemy.
my question to you, how do you respond to someone who roleplays as a conjurer? Do you nix all "magic" away, or only people who are seemingly able to manifest great feats?
