A Wizard has found a way to craft runes.
Air Runes: Engrave your rock with the Air Symbol, after that throw it from a hill. It will be charged.
Water Runes: Engrave your rock with the Water Symbol, after that dip it in water for 1 hour. It will be charged.
Fire Runes: Engrave your rock with the Fire Symbol, after that throw it inside a furnace. Pull it out and then burn it. It will be charged.
Earth Runes: NONE
Death Runes: Engrave your rock with the Death Symbol, after that kill someone and then absorb their energy into the rock. It will be charged.
Nature Runes: NONE
Mud Runes: Water runes and give it some dust.
Smoke runes: Air runes and burn it.
Mind Runes: Chop off someones brain and carve it into a rune with the mind symbol.
Body Runes: Cook someones body and then carve it into a rune with the body symbol, after that paint it blue.
Law Runes: Listen to a Judge or read a rule book with a Rock with a Law symbol carved to it.
Chaos Runes: Make a war and then throw those rocks with the Chaos Symbol Engraved.
Blood Runes: Drink Blood, Eat the rock engraved with the water symbol, but painted red so its blood. And then when you poop, you'll have a very sharp pain in your anus, and after its done, put your hand in and you'll find the Blood Rune.
Second Age: Same as First AGe
Third Age: Somebody found a portal to Rune Essence. But still the same way..
Fourth Age: Weird..
Air Runes: They cut off someones body, take the lungs, put the Rune Essence in a Saradomin Altar and then they charge it.
The rest are the same.
Fifth Age: Someone found a portal to the Rune Altars.
All ways are the same as today.
Sixth Age: Same as today
Seventh Age Prediction: Same way
Eight Age Prediction: The Altars will run out of powers and someone will find this book. They will do it as same in first age.
Ninth Age Prediction: They sure will find this book but Ninth Age+ are enchanted with spells that doesnt allow you to read them. Same as first age.
Tenth Age Prediction: They will become bored from doing it in the first age, especially the blood runes. So they do it like the second age.
Eleventh Age Prediction: They'll find a way to Make runes from their own Powers.
