Any thoughts on what this could be? Location of the Endless maybe? What’s interesting about it, is the fact that it looks straight towards the Silent Auditorium with a couple of symbols engraved into the stone
It’s location is far south (opposite the command spire)
If you’re referring to the Stone slabs with blue/yellow figures on them, those are Forerunner cylixes. They are used to hold(or imprison) DNA strains of species. Mainly it is used to catalog the universe’s random lifeforms in the chance that the Halo Array is fired and wipes out all life. These cylixes then will copy/clone the DNA and send them back to their respective planets to repopulate the galaxy
