Sovyrian Stone

The Sovyrian Stone is an enormous crystal, which the elves use to control the ancient portal arch that links Golarion to the fabled elven land of Sovyrian. In addition, the crystal also provides the power for all the aiudara or "elf gates" used by the elves to instantaneously travel across the world. Though the artifact is well known to all within Kyonin, it is well-hidden somewhere in the capital city of Iadara; few have ever laid eyes upon it.
