Vidh Zadh

Vadh Zadh is a powerful lich who lives in Mudwall. He is sometimes referred to as an arch-lich, despite the official title belonging to Vecna, Acererak, and Votuum. He has had many names over the years, including Victor Zarius and Vayduin Tal'Zergeiros. The name "Vidh Zadh" is draconic for "void elf" or "an elf who is devoid of life."

=== History ===
Vayduin was a sky elf scientist. He was in what was presumably a romantic relationship with Kethryllia Tal'Theda at some point before her marriage to Faethyn. He helped Keth with her work on Rama va Arel, specifically including the copying of her mental faculties to the AI which controlled the systems. Using the access she granted him, he was able to take control of the city during the Calamity, shutting it down rather than allowing it to be used to protect the Sky Elves. He thought the existence of the weapon too great a risk. Vayduin met his eventual demise with the core of Rama va Arel, attempting to contain the breach in its protective shielding during the assault of demons during the Calamity. During this process, he managed to maintain control of the core and himself, despite his flesh melting away from his work. 
=== Campaign One === 
During the events of campaign one, he was encountered by the party, now operating under the name Vidh Zadh. He owned a duplex dungeon or duplungeon; he rented out one half, while he lived in the other. In 893 A.C. the party sought out Vidh Zadh, having outdated information that he had an item they were looking for. They later returned to him, hoping he could help them create an item to help Belxari with her new-found sunlight weakness. He assisted them with this, creating armor from a collection of items they retrieved for him. He also later helped retrieve Darius' belongings from Arzarl Morumwood in Sunholme. The party would somewhat frequently return to him for assistance in powerful magical matters. Eventually, Caius attacked him in his tower, pretending to take his place when the party arrived in pursuit, leading to the first defeat of Caius and the rescue of Vidh Zadh. 
=== Campaign Two ===
The party first encountered Vidh Zadh during the early portion of campaign two, seeking for a way to hide Teer from Nox, and also in hopes that he could teleport them to the Hall of Beasts near Dunkelshwein. He agreed, their payment to retrieve some threads from inside a magical card, Donjon, from the Deck of Many Dungeons. He gave them that card, Don't Worry About It, as well as Teleportation Compass, then teleported them to Dunkelschwein. Several months later, Kiono would request that he take her as an apprentice for a time, to which he agreed. She and Teer once again returned to him later, seeking assistance in Kiono's modification of the Devoured ritual and identifying the curse placed on Teer by Enooto.
