Scholars in Keltia publish writings detailing the relationship between Nes and Volthaarius, the aspects of him as shared by Nes, such as his Silvery Mist and his dominion over dreams to essentially incriminate him in the attack on Crusader's Crest. They further add that it is clear that the murder of Nes has triggered an end to mortal dreams and nightmares. They specifically mention that Volthaarius may to go to such fatal and extreme measures if any were to threaten the dragonborn.
