The Decayed Compass of Uloho Grogeyz is a 2064 years old piece made by Uloho Grogeyz, a engineer living in Naqa.
Considering its age and the quality of the work, people consider it of no value.
It is engraved with african patterns and some symbols pertaining to Berber religion.
This piece doesn't exist, but as a legend. It is said that in the year 1935, Harry Grogeyz, the owner, made use of it in Nanjing to empower the Grogeyz family. Now it is lost, or broken, we will never know.
