The OSIRIS Shaft Mystery W/ Jimmy From Bright Insight

Hello Hunters,
This week ‪@BrightInsight‬ and I are theorising what we think the origins of The Osiris Shaft on the Giza Plateau.
We got special access to the shaft, thats not open to the public on our recent trip to Eygpt. Was it really the tomb of Osiris? How old do we think it could be? Why did they brick up a tunnel on the 3rd level?
Let us know your thoughts too!
