According to a legend, King Solomon was given the power to enslave and control demons using a ring. He built the temple via demons that he had enslaved.

Somebody in his administration made a record of the techniques Solomon used to control demons. After he died, he was buried along with his ring and the record of his techniques. A few generations Later, when they wanted to repair his tomb they found that record and the ring...and ever since they have been using them to make contact with the demons.
