Vess DeRogna

 is a half-elven mage and a member of the Cerberus Assembly, filling the role of Archmage of Antiquity. As an NPC, is played by Matthew Mercer.

Appearance
Lady Vess DeRogna is an half-elven woman with short, medium-brown hair. She is not young for an elf, but not as old as Ludinus Da'leth. She wears clothes of green and black, deep green with black designs across and around the edges of the billowing sleeves, and a number of rings and necklaces, each containing some sort of circular gem that dangles from them like a little collection of colors.

Personality
Caleb described her as "half a recluse", and a history buff who taught at the Soltryce Academy.

Background
A public recluse for most of her life, Vess was always a brilliant mage and dedicated historian. She was an instructor at the Soltryce Academy for over two decades where she unraveled a number of historical mysteries and pre-Calamity riddles - and hoarded some of the spoils for herself. She eventually assumed the position of Archmage of Antiquity after replacing her criminal predecessor, Lady Delilah Briarwood.

Lady Vess DeRogna was mentioned to be the Archmage of Antiquity.

Vess DeRogna was present in Felderwin when the Mighty Nein arrived, and was seen meeting Martinet Ludinus Da'leth when he Teleported in. They were talking together as they walked towards the ruins of the Brenatto Apothecary.

While in his cell, Yeza Brenatto described how "Lady DeRogna" would bring the Beacon from a secured place to his basement for experiments. She also threatened Luc's safety if Yeza ever shared his knowledge of their experiments with anyone.

Essek Thelyss confesses to having conspired with Ludinus and Trent Ikithon in the theft of the Beacons that sparked the war, and notes that while he never met DeRogna, he knew she helmed a period of experimentation with the Luxon Beacon. These were the only people he believed to have knowledge of the arrangement.

While the armada was sailing to the peace talks, the Ball-Eater was attacked by forces of Uk'otoa. In the immediate aftermath, Lady DeRogna used Dimension Door to reach the ship to intervene. The party lied and said it seemed like a random attack. Lady DeRogna accepted this, and invited the party to talk to her about work possibilities in the north once all of this was over. A few days later, Caleb and Beau flew to the Cerberus Assembly ship the Wind of Aeons to inspect the Luxon Beacon being carried to the parley. Martinet Ludinus Da'leth seemed genuinely surprised to learn the party had met Lady DeRogna, and that she had offered them work. Her purpose for being at the talks was to keep an eye on the perimeter and to hopefully discuss arcane projects between the Empire and the Dynasty if the peace talks were to go well.
