Rune

The Rune is a group of items added by Quark. They can be found in dungeons. They function as Enchanted Books; they can be used to give a tool or weapon an enchantment in an Anvil. The color of the Rune used will change the color of enchantment overlay of a tool or armor piece. Runes can also be used in End Portal Frames to color code portals. If two End Portals have the same configuration of runes they will link with each other and players are able to teleport between them. You need 12 Runes in a portal to activate it, they can not be mixed with Ender Eyes.
