Under a statue of the ancient ruler Glic are three shelves wide enough for two statuettes. Beneath the shelves are four statuettes with gnomish runes for G, F, C, and I.
Inscribed inside the inset square at the center of the room in gnomish is the puzzle:
“Geam, Iarann, Fahthast, and Cruaidh were officers in my stewardship. Of the four, all were different ages except the twins. Two of the four were of equal rank, though only one of these two commanded any of the others. Fahthast was the youngest, but the highest ranking, directly under my tutelage. The rest had ranks conforming to their age. Iarann envied his twin brother’s rank, but Geam, his commander, kept him from becoming demotivated.”
In an unbreakable crystal case are 4 keys one of which shatters each time all four statues are on the shelves in a wrong pattern.
