Lost Scrolls

The Lost Scrolls are a set of texts said to contain very powerful magical spells. The Prophecies storyline never goes over the scrolls in detail. However, it is mentioned that they contained many Orrian spells. We know that Vizier Khilbron used one of the spells to destroy the oncoming Charr, and unfortunately most of Orr. We also know that the scrolls contained the secrets to using capture signets.
