The Living String is a material in Bloodborne.
- Special material used in a Holy Chalice ritual.
- The immense brain that Mensis retrieved from the nightmare was indeed lined with eyes on the inside, but they were of an evil sort, and the brain itself was terribly rotten.
- But even still, it was a legitimate Great One, and left a relic. A living relic, at that, which is a precious thing indeed.
- It is important to kill the Brain of Mensis in the first playthrough, otherwise players will be forced to nearly complete another to reach the point where it becomes available again.
