"The last king of the Tenkay left the Red and Blue Rings when he deserted the island."
"The Blue Ring was left in the plane beyond the lighthouse. The catacombs were deemed enough of a deterrant to protect it."
"But the Red Ring, which was rather more dangerous, he left in the abandoned temple in the Kreniak Desert. Alber the Wise lived north of the temple on a small cattle ranch for many years, ostensibly to keep an eye on it."
