Crystal may be found in ages. It is used to make Mystcraft portals for quick entry into different ages. The portals do not need to have any specific dimensions, as long as they create some sort of a closed shape. To activate the portal, place a Book Receptacle on one of the crystals, and insert a linking or descriptive book.
Crystal is only found in ages generated by Descriptive Books which specify that there will be Crystal in the age, which is generated in random formations akin to that of Glowstone's generation. It is easiest to locate Crystal if the world is an End world or a Skylands world, as this will provide more exposed land for Crystal to generate.
