The Nether Scroll
Powers and abilities remain unknown. Valdis was able to use the scroll to banish the Cult Leader’s Devil half back into Hell.
Levith shared with you that the Nether Scrolls were found by the Nether Tribe when they came east after being banished by the Eldar. It was seen as a gift of the High Mage and helped teach the tribe how to manipulate magic.
The Nether Scrolls were encountered by the team in the lowest vault below the ruins of Mulhoránd. The scroll was in the center of a column of magical energy created by the Nexus.
