Also this is from the Relic grimoire I believe. " Bind yourself to the shield. Bind yourself to me. And if you abandon your purpose, let the Vault consume you, as it consumed me." Maybe this is telling us we can bring the relic all the way through the raid somehow, and if you mess up you have to wipe and start over. On one of the cards it talks about how the vex are trying to separate us from the shield throughout the whole vault of glass.
