Crypt of the Rune King

Publisher's blurb: A rocky cavern leads you down toward an ancient altar, the air smells of the dust of ages and two large statues loom above you. A ledger containing strange ciphers is sitting atop a pedestal, while four symbols have been carved into the tiles around the pedestal. Two large iron-bound gates guard the inner tombs and will not open no matter how hard they’re pushed. Inside this old place tombs lie broken and opened, although the damage looks like it may have been done from the inside… A final portcullis guards the vault of ancient treasures and tomes of mysterious power, watched over by a large tomb a top a staircase.
