Eye of Saradomin

The Eye of Saradomin is a legendary object, only mentioned in a hard-to-obtain conversation with Wizard Elriss. Apparently, this object was used to create all of the Runecrafting Altars and the Rune Essence. Therefore, the 'Eye of Saradomin' probably is another name for the Stone of Jas, as legend says that Guthix used this artefact to create the Essence and Altars, but it is not certain if it really is the same thing.
