Jas

Jas is believed to be an elder god, who existed even before Guthix had arrived and shaped Gielinor. Whether Jas created Gielinor is unknown, but he probably left with the other Elder Gods. The only thing that links back to him is the Stone of Jas, a strong magical object that illustrates the great might the Elder Gods have, even surpassing Guthix's power.

The main reason Jas is believed to be a person instead of a place or material are the words spoken by the Oracle: "Jas left a stone behind", and also the following quote from the quest diary after completing While Guthix Sleeps:

"I've seen a vision by touching the strange orb. It has communicated to me that it is 'The Stone of Jas', owned by Jas, and protected by creatures he has enslaved for the purpose - the Dragonkin. One of the first of the Fremennik tribe touched the Stone and it changed them drastically...this is how they became Lunar mages."
