Consumed By The Darkness.

The vault of glass. Often a debated topic by the warlocks of the upper order.

Who built it? When was it built? Does it have a higher purpose?

No one truly knows the answer. It's a place of true mystery and wonder. Often warlocks talk about wanting to and run surveys and tests on the rare metals that are placed around the vault.

Recently. After Oryx's arrival in the solar system and the discovery of the taken, questions have averted back to the vault. This time. About its effect to the light.

Do the vex know weakness in guardian's?
Can light be effected by time?
Can the Times Conflux - Atheon somehow alter the light in guardian's?

A failed expedition to the vault for a lonley hunter may just answer that question...
