Mages/Witches
Using magic can only be done when you chanted a specific verse with your name in it, and then stating your wish, as you offer a specific fruit of human intelligence (technology) by just touching it. The more advance the technology, the greater the magic will be given. It also works if your technology is more offensive, then it will be greater knowledge of arcane experience. The verse will be this one:
"Tree within the tree, great tree within the great tree, tree that has existed since the beginning, Tree of Genesis. My name is _______."
Humans: Using magic can only be used through Talismans, which are every day items with magic embedded into them (ie: Rings, Necklaces, bracelets, etc") Keep in mind, though, that Talismans have limit uses, and once those uses run out, the item is destroyed.
Types of Magic:
Offensive: Fire. Lightning. Etc.
Defensive: High speed movement (Like teleporting short distances. Flying long distances), Skin Hardening, Barriers, Force Pushing things away.
Warding Magic: Binding Circles(Stopping movement) Wards, etc.
