Chelchis, Kell of Stone
From Destiny 1 Wiki
Where is the Great Machine? Where is the Great Machine?- Chelchis, Kell of Stone
Chelchis, Kell of Stone was a Kell of the Fallen House of Stone who once "stood before the Maw". The Fallen still revere Chelchis in their songs. From artifact and weapon descriptions, it can be assumed that Chelchis was killed by Oryx himself and in his last moments, called out in vain for the Traveler, only to be crushed by the power of the Taken King.
