The Phee Hourglass is a relic of Pheebor.
A beautiful miniature hourglass, wrought of brass and crystal, and filled with fine, white sand.
It was sold for 1000 zorkmids (its true value is incalculable) thought that would remain forever a mystery, part of a greater, unknowable Magick.
A humble peasant-turned-adventurer discovered in 966 GUE that with the Hourglass you could travel in time, back to the days of the founding of Pheebor, and forward to the Final Conflagration.
