The Rimskull is an ancient, mysterious temple located deep within the Crystalpeak Mountains of Cyrendar.

The Rimskull appears as a great stone skull; with an opening built into its "mouth." It is believed that this temple was built a thousand years ago by a tribe of Stone Giants known as the Stor-Val, but its original purpose remains a mystery. The temple is essentially a great circular chamber built into the peak of Mt. Khodar, and is accessible only by a long winding stone stair built into the mountainside.

Inside the chamber are seven statues; each carved in the likeness of a wizard sitting upon an elaborate throne. The Thrones are carved with different symbols in the lost language of Iskamaic.
